Schema for describing Windows Installer database files (.msi/.msm/.pcp). This is the top-level container element for every wxs file. Among the possible children, the Bundle, Product, Module, Patch, and PatchCreation elements are analogous to the main function in a C program. There can only be one of these present when linking occurs. Product compiles into an msi file, Module compiles into an msm file, PatchCreation compiles into a pcp file. The Fragment element is an atomic unit which ultimately links into either a Product, Module, or PatchCreation. The Fragment can either be completely included or excluded during linking. Required version of the WiX toolset to compile this input file. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. This is the top-level container element for every wxi file. The root element for creating bundled packages. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. A URL for more information about the bundle to display in Programs and Features (also known as Add/Remove Programs).

All rights reserved.". Whether Packages and Payloads not assigned to a container should be added to the default attached container or if they should be external. The default is yes. Determines whether the bundle can be modified via the Programs and Features (also known as Add/Remove Programs). If the value is "button" then Programs and Features will show a single "Uninstall/Change" button. If the value is "yes" then Programs and Features will only show the "Uninstall" button". If the value is "no", the default, then a "Change" button is shown. See the DisableRemove attribute for information how to not display the bundle in Programs and Features. Determines whether the bundle can be removed via the Programs and Features (also known as Add/Remove Programs). If the value is "yes" then the "Uninstall" button will not be displayed. The default is "no" which ensures there is an "Uninstall" button to remove the bundle. If the "DisableModify" attribute is also "yes" or "button" then the bundle will not be displayed in Progams and Features and another mechanism (such as registering as a related bundle addon) must be used to ensure the bundle can be removed. A telephone number for help to display in Programs and Features (also known as Add/Remove Programs). A URL to the help for the bundle to display in Programs and Features (also known as Add/Remove Programs). Path to an icon that will replace the default icon in the final Bundle executable. This icon will also be displayed in Programs and Features (also known as Add/Remove Programs). The publisher of the bundle to display in Programs and Features (also known as Add/Remove Programs).

If the parent name does not actually exist, a virtual parent is created automatically. Path to a bitmap that will be shown as the bootstrapper application is being loaded. If this attribute is not specified, no splash screen will be displayed. Set this string to uniquely identify this bundle to its own BA, and to related bundles. The value of this string only matters to the BA, and its value has no direct effect on engine functionality. A URL for updates of the bundle to display in Programs and Features (also known as Add/Remove Programs). Unique identifier for a family of bundles. If two bundles have the same UpgradeCode the bundle with the highest version will be installed. The version of the bundle. Newer versions upgrade earlier versions of the bundles with matching UpgradeCodes. If the bundle is registered in Programs and Features then this attribute will be displayed in the Programs and Features user interface. The condition of the bundle. If the condition is not met, the bundle will refuse to run. Conditions are checked before the bootstrapper application is loaded (before detect), and thus can only reference built-in variables such as variables which indicate the version of the OS. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Provides information about an .exe so that the BA can request the engine to run it elevated from any secure location. The identifier of the ApprovedExeForElevation element. The key path. For security purposes, the root key will be HKLM and Variables are not supported. The value name. For security purposes, Variables are not supported.

An error is generated at build time if neither attribute is specified. The release type of the update bundle, such as Update, Security Update, Service Pack, etc. The default value is Update. Contains the chain of packages to install. Specifies whether the bundle will attempt to rollback packages executed in the chain. If "yes" is specified then when a vital package fails to install only that package will rollback and the chain will stop with the error. The default is "no" which indicates all packages executed during the chain will be rolledback to their previous state when a vital package fails. Specifies whether the bundle will attempt to create a system restore point when executing the chain. If "yes" is specified then a system restore point will not be created. The default is "no" which indicates a system restore point will be created when the bundle is installed, uninstalled, repaired, modified, etc. If the system restore point cannot be created, the bundle will log the issue and continue. Specifies whether the bundle will start installing packages while other packages are still being cached. If "yes", packages will start executing when a rollback boundary is encountered. The default is "no" which dictates all packages must be cached before any packages will start to be installed. Describes a single msi package to install. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The extension's CompilerExtension.ParseElement() method will be called with the package identifier as the first value in contextValues. Specifies whether the bundle will show the UI authored into the msi package. The default is "no" which means all information is routed to the bootstrapper application to provide a unified installation experience. If "yes" is specified the UI authored into the msi package will be displayed on top of any bootstrapper application UI. Specifies whether the bundle will allow individual control over the installation state of Features inside the msi package. Managing feature selection requires special care to ensure the install, modify, update and uninstall behavior of the package is always correct. The default is "no". Override the automatic per-machine detection of MSI packages and force the package to be per-machine. The default is "no", which allows the tools to detect the expected value. This attribute has been deprecated. When the value is "yes", the Binder will not read the MSI package to detect uncompressed files that would otherwise be automatically included in the Bundle as Payloads. The resulting Bundle may not be able to install the MSI package correctly. The default is "no". Specifies whether the MSI will be displayed in Programs and Features (also known as Add/Remove Programs). If "yes" is specified the MSI package information will be displayed in Programs and Features. The default "no" indicates the MSI will not be displayed. Describes a single msp package to install. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The extension's CompilerExtension.ParseElement() method will be called with the package identifier as the first value in contextValues. Specifies whether the bundle will show the UI authored into the msp package. The default is "no" which means all information is routed to the bootstrapper application to provide a unified installation experience. If "yes" is specified the UI authored into the msp package will be displayed on top of any bootstrapper application UI. Indicates the package must be executed elevated. The default is "no". Specifies whether to automatically slipstream the patch for any target msi packages in the chain. The default is "no". Even when the value is "no", you can still author the SlipstreamMsp element under MsiPackage elements as desired. Describes a single msu package to install. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The extension's CompilerExtension.ParseElement() method will be called with the package identifier as the first value in contextValues. A condition that determines if the package is present on the target system. This condition can use built-in variables and variables returned by searches. This condition is necessary because Windows doesn't provide a method to detect the presence of an MsuPackage. Burn uses this condition to determine how to treat this package during a bundle action; for example, if this condition is false or omitted and the bundle is being installed, Burn will install this package. The knowledge base identifier for the MSU. The KB attribute must be specified to enable the MSU package to be uninstalled. Even then MSU uninstallation is only supported on Windows 7 and later. When the KB attribute is specified, the Permanent attribute will the control whether the package is uninstalled. Describes a single exe package to install. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The extension's CompilerExtension.ParseElement() method will be called with the package identifier as the first value in contextValues. A condition that determines if the package is present on the target system. This condition can use built-in variables and variables returned by searches. This condition is necessary because Windows doesn't provide a method to detect the presence of an ExePackage. Burn uses this condition to determine how to treat this package during a bundle action; for example, if this condition is false or omitted and the bundle is being installed, Burn will install this package. The command-line arguments provided to the ExePackage during install. If this attribute is absent the executable will be launched with no command-line arguments. The command-line arguments to specify to indicate a repair. If the executable package can be repaired but does not require any special command-line arguments to do so then set the attribute's value to blank. To indicate that the package does not support repair, omit this attribute. The command-line arguments provided to the ExePackage during uninstall. If this attribute is absent the executable will be launched with no command-line arguments. To prevent an ExePackage from being uninstalled set the Permanent attribute to "yes". Indicates the package must be executed elevated. The default is "no". Indicates the communication protocol the package supports for extended progress and error reporting. The default is "none". Describes a rollback boundary in the chain. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The extension's CompilerExtension.ParseElement() method will be called with the rollback boundary identifier as the 'RollbackBoundaryId' key in contextValues. Identifier for this rollback boundary, for ordering and cross-referencing. If this attribute is not provided a stable identifier will be generated. Specifies whether the rollback boundary aborts the chain. The default "yes" indicates that if the rollback boundary is encountered then the chain will fail and rollback or stop. If "no" is specified then the chain should continue successfuly at the next rollback boundary. Location of the package to add to the bundle. The default value is the Name attribute, if provided. At a minimum, the SourceFile or Name attribute must be specified. The destination path and file name for this chain payload. Use this attribute to rename the chain entry point or extract it into a subfolder. The default value is the file name from the SourceFile attribute, if provided. At a minimum, the Name or SourceFile attribute must be specified. The use of '..' directories is not allowed. The URL to use to download the package. The following substitutions are supported: {0} is replaced by the package Id. {1} is replaced by the payload Id. {2} is replaced by the payload file name. Identifier for this package, for ordering and cross-referencing. The default is the Name attribute modified to be suitable as an identifier (i.e. invalid characters are replaced with underscores). The identifier of another package that this one should be installed after. By default the After attribute is set to the previous sibling package in the Chain or PackageGroup element. If this attribute is specified ensure that a cycle is not created explicitly or implicitly. The size this package will take on disk in bytes after it is installed. By default, the binder will calculate the install size by scanning the package (File table for MSIs, Payloads for EXEs) and use the total for the install size of the package. A condition to evaluate before installing the package. The package will only be installed if the condition evaluates to true. If the condition evaluates to false and the bundle is being installed, repaired, or modified, the package will be uninstalled. Whether to cache the package. The default is "yes". The identifier to use when caching the package. Specifies the display name to place in the bootstrapper application data manifest for the package. By default, ExePackages use the ProductName field from the version information, MsiPackages use the ProductName property, and MspPackages use the DisplayName patch metadata property. Other package types must use this attribute to define a display name in the bootstrapper application data manifest. Specifies the description to place in the bootstrapper application data manifest for the package. By default, ExePackages use the FileName field from the version information, MsiPackages use the ARPCOMMENTS property, and MspPackages use the Description patch metadata property. Other package types must use this attribute to define a description in the bootstrapper application data manifest. Name of a Variable that will hold the path to the log file. An empty value will cause the variable to not be set. The default is "WixBundleLog_[PackageId]" except for MSU packages which default to no logging. Name of a Variable that will hold the path to the log file used during rollback. An empty value will cause the variable to not be set. The default is "WixBundleRollbackLog_[PackageId]" except for MSU packages which default to no logging. Specifies whether the package can be uninstalled. The default is "no". Specifies whether the package must succeed for the chain to continue. The default "yes" indicates that if the package fails then the chain will fail and rollback or stop. If "no" is specified then the chain will continue even if the package reports failure. Whether the package payload should be embedded in a container or left as an external payload. By default, a Bundle will use the hash of a package to verify its contents. If this attribute is explicitly set to "no" and the package is signed with an Authenticode signature the Bundle will verify the contents of the package using the signature instead. Therefore, the default for this attribute could be considered to be "yes". It is unusual for "yes" to be the default of an attribute. In this case, the default was changed in WiX v3.9 after experiencing real world issues with Windows verifying Authenticode signatures. Since the Authenticode signatures are no more secure than hashing the packages directly, the default was changed. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. The extension's CompilerExtension.ParseAttribute() method will be called with the package identifier in contextValues["PackageId"]. Describes a package group to a bootstrapper. Identifier for package group. Create a reference to PackageGroup element that exists inside a Bundle or Fragment element. The identifier of the PackageGroup element to reference. The identifier of a package that this group should be installed after. Allows an MSI property to be set based on the value of a burn engine expression. The name of the MSI property to set. Burn controls the follow MSI properties so they cannot be set with MsiProperty: ACTION, ALLUSERS, REBOOT, REINSTALL, REINSTALLMODE The value to set the property to. This string is evaluated by the burn engine and can be as simple as a burn engine variable reference or as complex as a full expression. Specifies a patch included in the same bundle that is installed when the parent MSI package is installed. You can also specify that any MspPackage elements in the chain are automatically slipstreamed by setting the Slipstream attribute of an MspPackage to "yes". This will reduce the amount of authoring you need to write and will determine which msi packages can slipstream patches when building a bundle. The identifier for a MspPackage in the bundle. Describes a burn engine variable to define. Whether the value of the variable should be hidden. The name for the variable. Whether the variable should be persisted. Starting value for the variable. Type of the variable, inferred from the value if not specified. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Representation of a file that contains one or more files. The URL to use to download the container. This attribute is only valid when the container is detached. The following substitutions are supported: {0} is always null. {1} is replaced by the container Id. {2} is replaced by the container file name. The unique identifier for the container. If this attribute is not specified the Name attribute will be used. The file name for this container. A relative path may be provided to place the container in a sub-folder of the bundle. Indicates whether the container is "attached" to the bundle executable or placed external to the bundle extecutable as "detached". If this attribute is not specified, the default is to create a detached container. Create a reference to an existing Container element. The identifier of Container element to reference. Describes map of exit code returned from executable package to a bootstrapper behavior. Exit code returned from executable package. If no value is provided it means all values not explicitly set default to this behavior. Choose one of the supported behaviors error codes: success, error, scheduleReboot, forceReboot. Describes additional, conditional command-line arguments for an ExePackage. Additional command-line arguments to apply during package installation if Condition is true. Additional command-line arguments to apply during package uninstallation if Condition is true. Additional command-line arguments to apply during package repair if Condition is true. The condition that controls whether the command-line arguments specified in the InstallArgument, UninstallArgument, or RepairArgument attributes are appended to the command line passed to the ExePackage. Which attribute is used depends on the action being applied to the ExePackage. For example, when the ExePackage is being installed, the InstallArgument attribute value is appended to the command line when the ExePackage is executed. Describes a payload to a bootstrapper. The identifier of Payload element. Whether the payload should be embedded in a container or left as an external payload. Location of the source file. The destination path and file name for this payload. The default is the source file name. The use of '..' directories is not allowed. The URL to use to download the package. The following substitutions are supported: {0} is replaced by the package Id. {1} is replaced by the payload Id. {2} is replaced by the payload file name. By default, a Bundle will use a package's Authenticode signature to verify the contents. If the package does not have an Authenticode signature then the Bundle will use a hash of the package instead. Set this attribute to "yes" to suppress the default behavior and force the Bundle to always use the hash of the package even when the package is signed. Describes a payload group to a bootstrapper. PayloadGroups referenced from within a Bundle are tied to the Bundle. PayloadGroups referenced from a Fragment are tied to the context of whatever references them such as an ExePackage or MsiPackage. It is possible to share a PayloadGroup between multiple Packages and/or a Bundle by creating multiple references to it. Identifier for payload group. Create a reference to PayloadGroup element that exists inside a Bundle or Fragment element. The identifier of the PayloadGroup element to reference. Describes information about a remote file payload that is not available at the time of building the bundle.

The action to take on bundles related to this one. Detect is the default. Defines the update for a Bundle. The absolute path or URL to check for an update bundle. Currently the engine provides this value in the IBootstrapperApplication::OnDetectUpdateBegin() and otherwise ignores the value. In the future the engine will be able to acquire an update bundle from the location and determine if it is newer than the current executing bundle. The Product element is analogous to the main function in a C program. When linking, only one Product section can be given to the linker to produce a successful result. Using this element creates an msi file. You can specify any valid Windows code page by integer like 1252, or by web name like Windows-1252. See Code Pages for more information. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The product code GUID for the product. The code page integer value or web name for the resulting MSI. See remarks for more information. The decimal language ID (LCID) for the product. The manufacturer of the product. The descriptive name of the product. The upgrade code GUID for the product. The product's version string. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. The Module element is analogous to the main function in a C program. When linking, only one Module section can be given to the linker to produce a successful result. Using this element creates an msm file. You can specify any valid Windows code by by integer like 1252, or by web name like Windows-1252. See Code Pages for more information. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The name of the merge module (not the file name). The code page integer value or web name for the resulting MSM.

Only one of ExcludeExceptLanguage and ExcludeLanguage may be specified. Numeric language ID of the merge module in ExcludedID. The specified language will be excluded. Only one of ExcludeExceptLanguage and ExcludeLanguage may be specified. Minimum version excluded from a range. If not set, all versions before max are excluded. If neither max nor min, no exclusion based on version. Maximum version excluded from a range. If not set, all versions after min are excluded. If neither max nor min, no exclusion based on version. Defines the configurable attributes of merge module. Defines the name of the configurable item. Specifies the format of the data being changed. Specifies the type of the data being changed. Specifies a semantic context for the requested data. Specifies a default value for the item in this record if the merge tool declines to provide a value. Does not merge rule according to rules in MSI SDK. If yes, null is not a valid entry. Display name for authoring. Description for authoring. Location of chm file for authoring. Keyword into chm file for authoring. Specifies the configurable fields of a module database and provides a template for the configuration of each field.

Specifies the target column in the row named in the Row column. Provides a formatting template for the data being substituted into the target field specified by Table, Row, and Column. Specifies a table from the merge module that is not merged into an .msi file. If the table already exists in an .msi file, it is not modified by the merge. The specified table can therefore contain data that is unneeded after the merge. To minimize the size of the .msm file, it is recommended that developers remove unused tables from modules intended for redistribution rather than creating IgnoreTable elements for those tables. The name of the table in the merge module that is not to be merged into the .msi file. The Fragment element is the building block of creating an installer database in WiX. Once defined, the Fragment becomes an immutable, atomic unit which can either be completely included or excluded from a product. The contents of a Fragment element can be linked into a product by utilizing one of the many *Ref elements. When linking in a Fragment, it will be necessary to link in all of its individual units. For instance, if a given Fragment contains two Component elements, you must link both under features using ComponentRef for each linked Component. Otherwise, you will get a linker warning and have a floating Component that does not appear under any Feature. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Optional identifier for a Fragment. Should only be set by advanced users to tag sections. The Patch element is analogous to the main function in a C program. When linking, only one Patch section can be given to the linker to produce a successful result. Using this element creates an MSP file. You can specify any valid Windows code by by integer like 1252, or by web name like Windows-1252. See Code Pages for more information. The ClientPatchId attribute allows you to specify an easily referenced identity that you can use in product authoring. This identity prefixes properties added by WiX to a patch transform, such as ClientPatchId.PatchCode and ClientPatchId.AllowRemoval. If the patch code GUID is auto-generated you could not reference any properties using this auto-generated prefix. For example, if you were planning to ship a patch referred to as "QFE1" and needed to write your own registry values for Add/Remove Programs in product authoring such as the UninstallString for this patch, you could author a RegistryValue with the name UninstallString and the value [SystemFolder]msiexec.exe /package [ProductCode] /uninstall [QFE1.PatchCode]. In your patch authoring you would then set ClientPatchId to "QFE1" and WiX will add the QFE1.PatchCode property to the patch transform when the patch is created. If the Id attribute specified the patch code to be generated automatically, you could not reference the prefix.PatchCode property as shown above. The summary information is automatically populated from attribute values of the Patch element including the code page. If you want to override some of these summary information properties or use a different code page for the summary information itself, author the PatchInformation element. Optional element that allows overriding summary information properties. Indicates whether custom actions can be skipped when applying the patch. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Patch code for this patch. The code page integer value or web name for the resulting MSP. See remarks for more information. Whether this is an uninstallable patch. Category of updates. Recommended values are Critical Update, Hotfix, Security Rollup, Security Update, Service Pack, Update, Update Rollup. An easily referenced identity unique to a patch that can be used in product authoring. See remarks for more information. Flag used when creating a binary file patch. Default is "no". Don't use imagehlp.dll. Flag used when creating a binary file patch. Default is "no". Don't fail patch due to imagehlp failures. Flag used when creating a binary file patch. Default is "no". After matching decorated symbols, try to match remaining by undecorated names. Description of the patch. A title for the patch that is suitable for public display. In Add/Remove Programs from XP SP2 on. Optional comments for browsing. Vendor releasing the package Indicates that the patch targets the RTM version of the product or the most recent major upgrade patch. Author this optional property in minor update patches that contain sequencing information to indicate that the patch removes all patches up to the RTM version of the product, or up to the most recent major upgrade patch. This property is available beginning with Windows Installer 3.1. A URL that provides information specific to this patch. In Add/Remove Programs from XP SP2 on. If this attribute is set to 'yes' in all the patches to be applied in a transaction, the application of the patch is optimized if possible. Available beginning with Windows Installer 3.1. Name of the application or target product suite. When this attribute is set, patches for files greater than approximately 4 MB in size may be made smaller. Sets information in the patch transform that determines if the transform applies to an installed product and what errors should be ignored when applying the patch transform. A transform contains the differences between the target product and the upgraded product. When a transform or a patch (which contains transforms) is applied, the following properties of the installed product are validated against the properties of the target product stored in a transform. ProductCode ProductLanguage ProductVersion UpgradeCode Windows Installer simply validates that the ProductCode, ProductLanguage, and UpgradeCode of an installed product are equivalent to those propeties of the target product used to create the transform; however, the ProductVersion can be validated with a greater range of comparisons. You can compare up to the first three fields of the ProductVersion. Changes to the fourth field are not validated and are useful for small updates. You can also choose how to compare the target ProductVersion used to create the transform with the installed ProductVersion. For example, while the default value of 'Equals' is recommended, if you wanted a minor upgrade patch to apply to the target ProductVersion and all older products with the same ProductCode, you would use 'LesserOrEqual'. Requires that the installed ProductCode match the target ProductCode used to create the transform. The default is 'yes'. Requires that the installed ProductLanguage match the target ProductLanguage used to create the transform. The default is 'no'. Determines how many fields of the installed ProductVersion to compare. See remarks for more information. The default is 'Update'. Checks the major version. Checks the major and minor versions. Checks the major, minor, and update versions. Determines how the installed ProductVersion is compared to the target ProductVersion used to create the transform. See remarks for more information. The default is 'Equal'. Installed ProductVersion < target ProductVersion. Installed ProductVersion <= target ProductVersion. Installed ProductVersion = target ProductVersion. Installed ProductVersion >= target ProductVersion. Installed ProductVersion > target ProductVersion. Requires that the installed UpgradeCode match the target UpgradeCode used to create the transform. The default is 'yes'. Ignore errors when adding existing rows. The default is 'yes'. Ignore errors when adding existing tables. The default is 'yes'. Ignore errors when deleting missing rows. The default is 'yes'. Ignore errors when deleting missing tables. The default is 'yes'. Ignore errors when updating missing rows. The default is 'yes'. Ignore errors when changing the database code page. The default is 'no'. Indicates whether custom actions can be skipped when applying the patch. Skip property (type 51) and directory (type 35) assignment custom actions. Skip immediate custom actions that are not property or directory assignment custom actions. Skip custom actions that run within the script. Identifies a set of product versions. Identifier for a set of product versions. Collection of items that should be kept from the differences between two products. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Identifier which indicates a sequence family to which this patch belongs.

Searches for file and assigns to fullpath value of parent Property Unique identifier for the file search and external key into the Signature table. If this attribute value is not set then the parent element's @Id attribute is used. In prior versions of the WiX toolset, this attribute specified the short file name. This attribute's value may now be either a short or long file name. If a short file name is specified, the ShortName attribute may not be specified. If a long file name is specified, the LongName attribute may not be specified. If you wish to manually specify the short file name, then the ShortName attribute may be specified. The short file name of the file in 8.3 format. There is a Windows Installer bug which prevents the FileSearch functionality from working if both a short and long file name are specified. Since the Name attribute allows either a short or long name to be specified, it is the only attribute related to file names which should be specified. The minimum size of the file. The maximum size of the file. The minimum version of the file. The maximum version of the file. The minimum modification date and time of the file.

A reference to another FileSearch element must reference the same Id and the same Parent Id. If any of these attribute values are different you must instead use a FileSearch element. References an existing FileSearch element. Specify the Id to the FileSearch to reference. How To: Check the version number of a file during installation How To: Reference another DirectorySearch element How To: Get the parent directory of a file search Use the AssignToProperty attribute to search for a file but set the outer property to the directory containing the file. When this attribute is set to 'yes', you may only nest a FileSearch element with a unique Id or define no child element. When the parent DirectorySearch/@Depth attribute is greater than 0, the FileSearch/@Id attribute must be absent or the same as the parent DirectorySearch/@Id attribute value, unless the parent DirectorySearch/@AssignToProperty attribute value is 'yes'. Searches for directory and assigns to value of parent Property. Unique identifier for the directory search. Path on the user's system. Either absolute, or relative to containing directories. Depth below the path that the installer searches for the file or directory specified by the search. See remarks for more information. Set the value of the outer Property to the result of this search. See remarks for more information. How To: Reference another DirectorySearch element A reference to another DirectorySearch element must reference the same Id, the same Parent Id, and the same Path. If any of these attribute values are different you must instead use a DirectorySearch element. References an existing DirectorySearch element. Id of the search being referred to. This attribute is the signature of the parent directory of the file or directory in the Signature_ column. If this field is null, and the Path column does not expand to a full path, then all the fixed drives of the user's system are searched by using the Path. This field is a key into one of the following tables: the RegLocator, the IniLocator, the CompLocator, or the DrLocator tables. Path on the user's system. Either absolute, or relative to containing directories. Searches for file or directory and assigns to value of parent Property. The component ID of the component whose key path is to be used for the search. Must be file if last child is FileSearch element and must be directory if last child is DirectorySearch element. The key path of the component is a directory. The key path of the component is a file. This is the default value. Searches for file, directory or registry key and assigns to value of parent Property External key into the Signature table. The field in the .ini line. If field is Null or 0, the entire line is read. The key value within the section. In prior versions of the WiX toolset, this attribute specified the short name. This attribute's value may now be either a short or long name. If a short name is specified, the ShortName attribute may not be specified. If a long name is specified, the LongName attribute may not be specified. Also, if this value is a long name, the ShortName attribute may be omitted to allow WiX to attempt to generate a unique short name. However, if you wish to manually specify the short name, then the ShortName attribute may be specified. The localizable .ini file section. The short name of the file in 8.3 format. This attribute should only be set if the user wants to manually specify the short name. Must be file if last child is FileSearch element and must be directory if last child is DirectorySearch element. A directory location. A file location. This is the default value. A raw .ini value. How To: Read a registry entry during installation When the Type attribute value is 'directory' the registry value must specify the path to a directory excluding the file name. When the Type attribute value is 'file' the registry value must specify the path to a file including the file name; however, if there is no child FileSearch element the parent directory of the file is returned. The FileSearch element requires that you author the name of the file you are searching for. If you do not know the file name you must set the Type attribute to 'raw' to return the full file path including the file name. Searches for file, directory or registry key and assigns to value of parent Property Signature to be used for the file, directory or registry key being searched for. Root key for the registry value. HKEY_CLASSES_ROOT HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USERS Key for the registry value. Registry value name. If this value is null, then the value from the key's unnamed or default value, if any, is retrieved. The value must be 'file' if the child is a FileSearch element, and must be 'directory' if child is a DirectorySearch element. The registry value contains the path to a directory. The registry value contains the path to a file. To return the full file path you must add a FileSearch element as a child of this element; otherwise, the parent directory of the file path is returned. Sets the raw value from the registry value. Please note that this value will contain a prefix as follows:DWORDStarts with '#' optionally followed by '+' or '-'.REG_BINARYStarts with '#x' and the installer converts and saves each hexadecimal digit (nibble) as an ASCII character prefixed by '#x'.REG_EXPAND_SZStarts with '#%'.REG_MULTI_SZStarts with '[~]' and ends with '[~]'.REG_SZNo prefix, but if the first character of the registry value is '#', the installer escapes the character by prefixing it with another '#'. Instructs the search to look in the 64-bit registry when the value is 'yes'. When the value is 'no', the search looks in the 32-bit registry. The default value is based on the platform set by the -arch switch to candle.exe or the InstallerPlatform property in a .wixproj MSBuild project: For x86 and ARM, the default value is 'no'. For x64 and IA64, the default value is 'yes'. References an existing RegistrySearch element. Specify the Id of the RegistrySearch to reference. Sets the parent of a nested DirectorySearch element to CCP_DRIVE. Adds a row to the CCPSearch table. Starts searches from the CCP_DRIVE. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. How To: Check the version number of a file during installation Property value for a Product or Module. Starts searches from the CCP_DRIVE. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Unique identifier for Property. Sets a default value for the property. The value will be overwritten if the Property is used for a search. Adds a row to the CCPSearch table. This attribute is only valid when this Property contains a search element. Denotes that the Property is saved during admininistrative installation. See the AdminProperties Property for more information. Denotes that the Property can be passed to the server side when doing a managed installation with elevated privileges. See the SecureCustomProperties Property for more information. Denotes that the Property is not logged during installation. See the MsiHiddenProperties Property for more information. Use to suppress modularization of this property identifier in merge modules. Using this functionality is strongly discouraged; it should only be necessary as a workaround of last resort in rare scenarios. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. How To: Check for .NET Framework versions Reference to a Property value. Identifier of Property to reference. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Shortcut, default target is parent File, CreateFolder, or Component's Directory How To: Create a shortcut on the Start Menu Unique identifier for the shortcut. This value will serve as the primary key for the row. Identifier reference to Directory element where shortcut is to be created. When nested under a Component element, this attribute's value will default to the parent directory. Otherwise, this attribute is required. In prior versions of the WiX toolset, this attribute specified the short name. This attribute's value may now be either a short or long name. If a short name is specified, the ShortName attribute may not be specified. If a long name is specified, the LongName attribute may not be specified. Also, if this value is a long name, the ShortName attribute may be omitted to allow WiX to attempt to generate a unique short name. However, if this name collides with another shortcut or you wish to manually specify the short name, then the ShortName attribute may be specified. The short name of the shortcut in 8.3 format. This attribute should only be set if there is a conflict between generated short names or the user wants to manually specify the short name. This attribute can only be set if this Shortcut element is nested under a Component element. When nested under a Component element, this attribute's value will default to the parent directory. This attribute's value is the target for a non-advertised shortcut. This attribute is not valid for advertised shortcuts. If you specify this value, its value should be a property identifier enclosed by square brackets ([ ]), that is expanded into the file or a folder pointed to by the shortcut. The localizable description for the shortcut. The command-line arguments for the shortcut. Note that the resolution of properties in the Arguments field is limited. A property formatted as [Property] in this field can only be resolved if the property already has the intended value when the component owning the shortcut is installed. For example, for the argument "[#MyDoc.doc]" to resolve to the correct value, the same process must be installing the file MyDoc.doc and the component that owns the shortcut. The hotkey for the shortcut. The low-order byte contains the virtual-key code for the key, and the high-order byte contains modifier flags. This must be a non-negative number. Authors of installation packages are generally recommend not to set this option, because this can add duplicate hotkeys to a users desktop. In addition, the practice of assigning hotkeys to shortcuts can be problematic for users using hotkeys for accessibility. Identifier reference to Icon element. The Icon identifier should have the same extension as the file that it points at. For example, a shortcut to an executable (e.g. "my.exe") should reference an Icon with identifier like "MyIcon.exe" Identifier reference to Icon element. The shortcut target will be displayed using the SW_SHOWNORMAL attribute. The shortcut target will be displayed using the SW_SHOWMINNOACTIVE attribute. The shortcut target will be displayed using the SW_SHOWMAXIMIZED attribute. Directory identifier (or Property identifier that resolves to a directory) that resolves to the path of the working directory for the shortcut. Specifies if the shortcut should be advertised or not. Note that advertised shortcuts always point at a particular application, identified by a ProductCode, and should not be shared between applications. Advertised shortcuts only work for the most recently installed application, and are removed when that application is removed. The default value is 'no'. The Formatted string providing the full path to the language neutral file containing the MUI Manifest. Generally authored using [#filekey] form. When this attribute is specified, the DisplayResourceId attribute must also be provided. This attribute is only used on Windows Vista and above. If this attribute is not populated and the install is running on Vista and above, the value in the Name attribute is used.

When under a Registry element, this cannot be used if the Action attribute's value is remove or removeKeyOnInstall. This element is only available when installing with MSI 5.0. For downlevel support, see the PermissionEx element from the WixUtilExtension. Optional condition that controls whether the permissions are applied. Primary key used to identify this particular entry. If this is not specified the parent element's Id attribute will be used instead. Security descriptor to apply to parent object. Copy or move an existing file on the target machine, or copy a file that is being installed, to another destination. When this element is nested under a File element, the parent file will be installed, then copied to the specified destination if the parent component of the file is selected for installation or removal. When this element is nested under a Component element and no FileId attribute is specified, the file to copy or move must already be on the target machine. When this element is nested under a Component element and the FileId attribute is specified, the specified file is installed, then copied to the specified destination if the parent component is selected for installation or removal (use this option to control the copy of a file in a different component by the parent component's installation state). If the specified destination directory is the same as the directory containing the original file and the name for the proposed source file is the same as the original, then no action takes place. Primary key used to identify this particular entry. This attribute cannot be specified if the element is nested under a File element. Set this attribute's value to the identifier of a file from a different component to copy it based on the install state of the parent component. This attribute cannot be specified if the element is nested under a File element or the FileId attribute is specified. Set this value to the source directory from which to copy or move an existing file on the target machine. This Directory must exist in the installer database at creation time. This attribute cannot be specified in conjunction with SourceProperty. This attribute cannot be specified if the element is nested under a File element or the FileId attribute is specified. Set this value to a property that will have a value that resolves to the full path of the source directory (or full path including file name if SourceName is not specified). The property does not have to exist in the installer database at creation time; it could be created at installation time by a custom action, on the command line, etc. This attribute cannot be specified in conjunction with SourceDirectory. This attribute cannot be specified if the element is nested under a File element or the FileId attribute is specified. Set this value to the localizable name of the file(s) to be copied or moved. All of the files that match the wild card will be removed from the specified directory. The value is a filename that may also contain the wild card characters "?" for any single character or "*" for zero or more occurrences of any character. If this attribute is not specified (and this element is not nested under a File element or specify a FileId attribute) then the SourceProperty attribute should be set to the name of a property that will resolve to the full path of the source filename. If the value of this attribute contains a "*" wildcard and the DestinationName attribute is specified, all moved or copied files retain the file names from their sources. Set this value to the destination directory where an existing file on the target machine should be moved or copied to. This Directory must exist in the installer database at creation time. This attribute cannot be specified in conjunction with DestinationProperty. Set this value to a property that will have a value that resolves to the full path of the destination directory. The property does not have to exist in the installer database at creation time; it could be created at installation time by a custom action, on the command line, etc. This attribute cannot be specified in conjunction with DestinationDirectory. In prior versions of the WiX toolset, this attribute specified the short file name. Now set this value to the localizable name to be given to the original file after it is moved or copied. If this attribute is not specified, then the destination file is given the same name as the source file. If a short file name is specified, the DestinationShortName attribute may not be specified. If a long file name is specified, the DestinationLongName attribute may not be specified. Also, if this value is a long file name, the DestinationShortName attribute may be omitted to allow WiX to attempt to generate a unique short file name. However, if this name collides with another file or you wish to manually specify the short file name, then the DestinationShortName attribute may be specified. The short file name of the file in 8.3 format. This attribute should only be set if there is a conflict between generated short file names or you wish to manually specify the short file name. This attribute cannot be specified if the element is nested under a File element or the FileId attribute is specified. In other cases, if the attribute is not specified, the default value is "no" and the file is copied, not moved. Set the value to "yes" in order to move the file (thus deleting the source file) instead of copying it. File specification for File table, must be child node of Component. How To: Add a file to your installer Used to configure the ACLs for this file. Can also configure the ACLs for this file. Used to create a duplicate of this file elsewhere. Target of the shortcut will be set to this file. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. The unique identifier for this File element. If you omit Id, it defaults to the file name portion of the Source attribute, if specified. May be referenced as a Property by specifying [#value]. Set this attribute to make this file a companion child of another file. The installation state of a companion file depends not on its own file versioning information, but on the versioning of its companion parent. A file that is the key path for its component can not be a companion file (that means this attribute cannot be set if KeyPath="yes" for this file). The Version attribute cannot be set along with this attribute since companion files are not installed based on their own version. In prior versions of the WiX toolset, this attribute specified the short file name. This attribute's value may now be either a short or long file name. If a short file name is specified, the ShortName attribute may not be specified. If a long file name is specified, the LongName attribute may not be specified. Also, if this value is a long file name, the ShortName attribute may be omitted to allow WiX to attempt to generate a unique short file name. However, if this name collides with another file or you wish to manually specify the short file name, then the ShortName attribute may be specified. Finally, if this attribute is omitted then its default value is the file name portion of the Source attribute, if one is specified, or the value of the Id attribute, if the Source attribute is omitted or doesn't contain a file name. Set to yes in order to force this file to be the key path for the parent component. The short file name of the file in 8.3 format. This attribute should only be set if there is a conflict between generated short file names or the user wants to manually specify the short file name. Set to yes in order to have the file's read-only attribute set when it is installed on the target machine. Set to yes in order to have the file's hidden attribute set when it is installed on the target machine. Set to yes in order to have the file's system attribute set when it is installed on the target machine. If a file is vital, then installation cannot proceed unless the file is successfully installed. The user will have no option to ignore an error installing this file. If an error occurs, they can merely retry to install the file or abort the installation. The default is "yes," unless the -sfdvital switch (candle.exe) or SuppressFileDefaultVital property (.wixproj) is used. This attribute should be set to "yes" for every executable file in the installation that has a valid checksum stored in the Portable Executable (PE) file header. Only those files that have this attribute set will be verified for valid checksum during a reinstall. Sets the file's source type compression. A setting of "yes" or "no" will override the setting in the Word Count Summary Property. A list of paths, separated by semicolons, that represent the paths to be searched to find the imported DLLs. The list is usually a list of properties, with each property enclosed inside square brackets. The value may be set to an empty string. Including this attribute will cause an entry to be generated for the file in the BindImage table. The cost of registering the file in bytes. This must be a non-negative number. Including this attribute will cause an entry to be generated for the file in the SelfReg table. Causes an entry to be generated for the file in the Font table with no FontTitle specified. This attribute is intended to be used to register the file as a TrueType font. Causes an entry to be generated for the file in the Font table with the specified FontTitle. This attribute is intended to be used to register the file as a non-TrueType font. This is the default language of this file. The linker will replace this value from the value in the file if the suppress files option is not used. This is the default size of this file. The linker will replace this value from the value in the file if the suppress files option is not used. This is the default version of this file. The linker will replace this value from the value in the file if the suppress files option is not used. Specifies if this File is a Win32 Assembly or .NET Assembly that needs to be installed into the Global Assembly Cache (GAC). If the value is '.net' or 'win32', this file must also be the key path of the Component. The file is a .NET Framework assembly. The file is not a .NET Framework or Win32 assembly. This is the default value. The file is a Win32 assembly. Specifies the file identifier of the manifest file that describes this assembly. The manifest file should be in the same component as the assembly it describes. This attribute may only be specified if the Assembly attribute is set to '.net' or 'win32'. Specifies the file identifier of the application file. This assembly will be isolated to the same directory as the application file. If this attribute is absent, the assembly will be installed to the Global Assembly Cache (GAC). This attribute may only be specified if the Assembly attribute is set to '.net' or 'win32'. Specifies the architecture for this assembly. This attribute should only be used on .NET Framework 2.0 or higher assemblies. The file is a .NET Framework assembly that is processor-neutral. The file is a .NET Framework assembly for the x86 processor. The file is a .NET Framework assembly for the x64 processor. The file is a .NET Framework assembly for the ia64 processor. The value of this attribute should correspond to the Id attribute of a Media element authored elsewhere. By creating this connection between a file and its media, you set the packaging options to the values specified in the Media element (values such as compression level, cab embedding, etc...). Specifying the DiskId attribute on the File element overrides the default DiskId attribute from the parent Component element. If no DiskId attribute is specified, the default is "1". This DiskId attribute is ignored when creating a merge module because merge modules do not have media. Specifies the path to the File in the build process. Overrides default source path set by parent directories and Name attribute. This attribute must be set if no source information can be gathered from parent directories. For more information, see Specifying source files. This attribute must be set for patch-added files. Each patch should be assigned a different patch group number. Patch groups numbers must be greater 0 and should be assigned consecutively. For example, the first patch should use PatchGroup='1', the second patch will have PatchGroup='2', etc... Prevents the updating of the file that is in fact changed in the upgraded image relative to the target images. Set to indicate that the patch is non-vital. Set if the entire file should be installed rather than creating a binary patch. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Use several of these elements to specify each registry value in a multiString registry value. This element cannot be used if the Value attribute is specified unless the Type attribute is set to 'multiString'. The values should go in the text area of the MultiStringValue element. Used for organization of child RegistryValue elements or to create a registry key (and optionally remove it during uninstallation). How To: Read a registry entry during installation How To: Write a registry entry during installation ACL permission Can also configure the ACLs for this registry key. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Primary key used to identify this particular entry. If this attribute is not specified, an identifier will be generated by hashing the parent Component identifier, Root, Key, and Name. The Action attribute has been deprecated. In most cases, you can simply omit @Action. If you need to force Windows Installer to create an empty key or recursively delete the key, use the ForceCreateOnInstall or ForceDeleteOnUninstall attributes instead. Creates the key, if absent, when the parent component is installed. Creates the key, if absent, when the parent component is installed then remove the key with all its values and subkeys when the parent component is uninstalled. Note that this value is useful only if your program creates additional values or subkeys under this key and you want an uninstall to remove them. MSI already removes all values and subkeys that it creates, so this option just adds additional overhead to uninstall. Does nothing; this element is used merely in WiX authoring for organization and does nothing to the final output. This is the default value. Set this attribute to 'yes' to create an empty key, if absent, when the parent component is installed. This value is needed only to create an empty key with no subkeys or values. Windows Installer creates keys as needed to store subkeys and values. The default is "no". Set this attribute to 'yes' to remove the key with all its values and subkeys when the parent component is uninstalled. Note that this value is useful only if your program creates additional values or subkeys under this key and you want an uninstall to remove them. MSI already removes all values and subkeys that it creates, so this option just adds additional overhead to uninstall. The default is "no". The localizable key for the registry value. If the parent element is a RegistryKey, this value may be omitted to use the path of the parent, or if its specified it will be appended to the path of the parent. The predefined root key for the registry value. Used to create a registry value. For multi-string values, this can be used to prepend or append values. For legacy authoring: Use several of these elements to specify each registry value in a multiString registry value. This element cannot be used if the Value attribute is specified unless the Type attribute is set to 'multiString'. The values should go in the text area of the RegistryValue element. How To: Write a registry entry during installation Can also configure the ACLs for this registry value. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Primary key used to identify this particular entry. If this attribute is not specified, an identifier will be generated by hashing the parent Component identifier, Root, Key, and Name. The predefined root key for the registry value. The localizable key for the registry value. If the parent element is a RegistryKey, this value may be omitted to use the path of the parent, or if its specified it will be appended to the path of the parent. The localizable registry value name. If this attribute is not provided the default value for the registry key will be set instead. The Windows Installer allows several special values to be set for this attribute. You should not use them in WiX. Instead use appropriate values in the Action attribute to get the desired behavior. Set this attribute to the localizable registry value. This value is formatted. The Windows Installer allows several special values to be set for this attribute. You should not use them in WiX. Instead use appropriate values in the Type attribute to get the desired behavior. Set this attribute to the type of the desired registry key. This attribute must be specified whenever the Value attribute or a child RegistryValue element is specified. This attribute should only be set when the value of the Action attribute does not include the word 'remove'. The value is interpreted and stored as a string (REG_SZ). The value is interpreted and stored as an integer (REG_DWORD). The value is interpreted and stored as a hexadecimal value (REG_BINARY). The value is interpreted and stored as an expandable string (REG_EXPAND_SZ). The value is interpreted and stored as a multiple strings (REG_MULTI_SZ). Please note that this value will only result in a multi-string value if there is more than one registry value or the Action attribute's value is 'append' or 'prepend'. Otherwise a string value will be created. This is the action that will be taken for this registry value. Appends the specified value(s) to a multiString registry value. Prepends the specified value(s) to a multiString registry value. Writes a registry value. This is the default value. Set this attribute to 'yes' to make this registry key the KeyPath of the parent component. Only one resource (registry, file, etc) can be the KeyPath of a component. Used for removing registry keys and all child keys either during install or uninstall. Primary key used to identify this particular entry. If this attribute is not specified, an identifier will be generated by hashing the parent Component identifier, Root, Key, and Name. This is the action that will be taken for this registry value.

The Windows Installer allows several special values to be set for this attribute. You should not use them in WiX. Instead use appropriate values in the Type attribute to get the desired behavior. This attribute cannot be specified if the Action attribute's value contains the word 'remove'. Remove a file(s) if the parent component is selected for installation or removal. Multiple files can be removed by specifying a wildcard for the value of the Name attribute. By default, the source directory of the file is the directory of the parent component. This can be overridden by specifying the Directory attribute with a value corresponding to the Id of the source directory, or by specifying the Property attribute with a value corresponding to a property that will have a value that resolves to the full path to the source directory. Primary key used to identify this particular entry. Overrides the directory of the parent component with a specific Directory. This Directory must exist in the installer database at creation time. This attribute cannot be specified in conjunction with the Property attribute. Overrides the directory of the parent component with the value of the specified property. The property should have a value that resolves to the full path of the source directory. The property does not have to exist in the installer database at creation time; it could be created at installation time by a custom action, on the command line, etc. This attribute cannot be specified in conjunction with the Directory attribute. This value should be set to the localizable name of the file(s) to be removed. All of the files that match the wild card will be removed from the specified directory. The value is a filename that may also contain the wild card characters "?" for any single character or "*" for zero or more occurrences of any character. In prior versions of the WiX toolset, this attribute specified the short file name. This attribute's value may now be either a short or long file name. If a short file name is specified, the ShortName attribute may not be specified. If a long file name is specified, the LongName attribute may not be specified. Also, if this value is a long file name, the ShortName attribute may be omitted to allow WiX to attempt to generate a unique short file name. However, if you wish to manually specify the short file name, then the ShortName attribute may be specified. The short file name of the file in 8.3 format. This attribute should only be set if you want to manually specify the short file name. This value determines the time at which the file(s) may be removed. For 'install', the file will be removed only when the parent component is being installed (msiInstallStateLocal or msiInstallStateSource); for 'uninstall', the file will be removed only when the parent component is being removed (msiInstallStateAbsent); for 'both', the file will be removed in both cases. Remove an empty folder if the parent component is selected for installation or removal. By default, the folder is the directory of the parent component. This can be overridden by specifying the Directory attribute with a value corresponding to the Id of the directory, or by specifying the Property attribute with a value corresponding to a property that will have a value that resolves to the full path of the folder. Primary key used to identify this particular entry. Overrides the directory of the parent component with a specific Directory. This Directory must exist in the installer database at creation time. This attribute cannot be specified in conjunction with the Property attribute. Overrides the directory of the parent component with the value of the specified property. The property should have a value that resolves to the full path of the source directory. The property does not have to exist in the installer database at creation time; it could be created at installation time by a custom action, on the command line, etc. This attribute cannot be specified in conjunction with the Directory attribute. This value determines the time at which the folder may be removed, based on the install/uninstall of the parent component. For 'install', the folder will be removed only when the parent component is being installed (msiInstallStateLocal or msiInstallStateSource); for 'uninstall', the folder will be removed only when the parent component is being removed (msiInstallStateAbsent); for 'both', the folder will be removed in both cases. Create folder as part of parent Component. Non-advertised shortcut to this folder, Shortcut Target is preset to the folder ACL permission Can also configure the ACLs for this folder. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Identifier of Directory to create. Defaults to Directory of parent Component. Optional way for defining AppData, generally used for complex CDATA. Qualified published component for parent Component A string GUID that represents the category of components being grouped together. A text string that qualifies the value in the Id attribute. A qualifier is used to distinguish multiple forms of the same Component, such as a Component that is implemented in multiple languages. An optional localizable text describing the category. The string is commonly parsed by the application and can be displayed to the user. It should describe the category. Feature that controls the advertisement of the category. Defaults to the primary Feature for the parent Component . MIME content-type for an Extension Whether this MIME is to be advertised. The default is to match whatever the parent extension element uses. If the parent element is not advertised, then this element cannot be advertised either. This is the identifier for the MIME content. It is commonly written in the form of type/format. Class ID for the COM server that is to be associated with the MIME content. If 'yes', become the content type for the parent Extension. The default value is 'no'. Verb definition for an Extension. When advertised, this element creates a row in the Verb table. When not advertised, this element creates the appropriate rows in Registry table. The verb for the command. The localized text displayed on the context menu. Value for the command arguments. Note that the resolution of properties in the Argument field is limited. A property formatted as [Property] in this field can only be resolved if the property already has the intended value when the component owning the verb is installed. For example, for the argument "[#MyDoc.doc]" to resolve to the correct value, the same process must be installing the file MyDoc.doc and the component that owns the verb. The sequence of the commands. Only verbs for which the Sequence is specified are used to prepare an ordered list for the default value of the shell key. The Verb with the lowest value in this column becomes the default verb. Used only for Advertised verbs. Either this attribute or the TargetProperty attribute must be specified for a non-advertised verb. The value should be the identifier of the target file to be executed for the verb. Either this attribute or the TargetFile attribute must be specified for a non-advertised verb. The value should be the identifier of the property which will resolve to the path to the target file to be executed for the verb. Extension for a Component MIME and Verbs can be associated with Extensions This is simply the file extension, like "doc" or "xml". Do not include the preceding period. The MIME type that is to be written. Whether this extension is to be advertised. The default is "no". Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Register a type library (TypeLib). Please note that in order to properly use this non-advertised, you will need use this element with Advertise='no' and also author the appropriate child Interface elements by extracting them from the type library itself. The GUID that identifes the type library. Value of 'yes' will create a row in the TypeLib table. Value of 'no' will create rows in the Registry table. The default value is 'no'. Value of 'yes' means the type library describes controls, and should not be displayed in type browsers intended for nonvisual objects. This attribute can only be set if Advertise='no'. The cost associated with the registration of the type library in bytes. This attribute cannot be set if Advertise='no'. The localizable description of the type library. Value of 'yes' means the type library exists in a persisted form on disk. This attribute can only be set if Advertise='no'. The identifier of the Directory element for the help directory. Value of 'yes' means the type library should not be displayed to users, although its use is not restricted. Should be used by controls. Hosts should create a new type library that wraps the control with extended properties. This attribute can only be set if Advertise='no'. The language of the type library. This must be a non-negative integer. The major version of the type library. The value should be an integer from 0 - 255. The minor version of the type library. The value should be an integer from 0 - 255. The resource id of a typelib. The value is appended to the end of the typelib path in the registry. Value of 'yes' means the type library is restricted, and should not be displayed to users. This attribute can only be set if Advertise='no'. ProgId registration for parent Component. If ProgId has an associated Class, it must be a child of that element. The version-independent ProgId must be the first child element of actual ProgId. Nesting other ProgId elements within the Version-independent ProgId will create COM+ aliases, see http://support.microsoft.com/kb/305745 for more information. Extensions that refer to this ProgId For an advertised ProgId, the Id of an Icon element. For a non-advertised ProgId, this is the Id of a file containing an icon resource. Specifies that the associated ProgId should not be opened by users. The value is presented as a warning to users. An empty string is also valid for this attribute. Application ID containing DCOM information for the associated application GUID. If this element is nested under a Fragment, Module, or Product element, it must be advertised. When being used in unadvertised mode, the attributes in the AppId element correspond to registry keys as follows (values that can be specified in authoring are in bold): IdIn General [HKCR\AppID\{Id}]Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}]ActivateAtStorageIn General [HKCR\AppID\{Id}] ActivateAtStorage="ActivateAtStorage" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] ActivateAtStorage="Y" DescriptionIn General [HKCR\AppID\{Id}] @="Description" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] @="My AppId Description" DllSurrogateIn General [HKCR\AppID\{Id}] DllSurrogate="DllSurrogate" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] DllSurrogate="C:\surrogate.exe" LocalServiceIn General [HKCR\AppID\{Id}] LocalService="LocalService" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] LocalService="MyServiceName" RemoteServerNameIn General [HKCR\AppID\{Id}] RemoteServerName="RemoteServerName" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] RemoteServerName="MyRemoteServer" RunAsInteractiveUserIn General [HKCR\AppID\{Id}] RunAs="RunAsInteractiveUser" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] RunAs="Interactive User" ServiceParametersIn General [HKCR\AppID\{Id}] ServiceParameters="ServiceParameters" Specific Example [HKCR\AppID\{01234567-89AB-CDEF-0123-456789ABCDEF}] ServiceParameters="-param" Set this value to 'yes' to configure the client to activate on the same system as persistent storage. Set this value to 'yes' in order to create a normal AppId table row. Set this value to 'no' in order to generate Registry rows that perform similar registration (without the often problematic Windows Installer advertising behavior). Set this value to the description of the AppId. It can only be specified when the AppId is not being advertised. Set this value to specify that the class is a DLL that is to be activated in a surrogate EXE process, and the surrogate process to be used is the path of a surrogate EXE file specified by the value. Set this value to the AppID GUID that corresponds to the named executable. Set this value to the name of a service to allow the object to be installed as a Win32 service. Set this value to the name of the remote server to configure the client to request the object be run at a particular machine whenever an activation function is called for which a COSERVERINFO structure is not specified. Set this value to 'yes' to configure a class to run under the identity of the user currently logged on and connected to the interactive desktop when activated by a remote client without being written as a Win32 service.

The Class identifier (CLSID) of a COM server. The server context(s) for this COM server. This attribute is optional for VB6 libraries that are marked "PublicNotCreateable". Class elements marked Advertised must specify at least one server context. It is most common for there to be a single value for the Context attribute. A 16-bit local server application. A 32-bit local server application. A 16-bit in-process server DLL. A 32-bit in-process server DLL. Localized description associated with the Class ID and Program ID. This attribute is only allowed when a Class is advertised. Using this attribute will reference an Application ID containing DCOM information for the associated application GUID. The value must correspond to an AppId/@Id of an AppId element nested under a Fragment, Module, or Product element. To associate an AppId with a non-advertised class, nest the class within a parent AppId element. The file providing the icon associated with this CLSID. Reference to an Icon element (should match the Id attribute of an Icon element). This is currently not supported if the value of the Advertise attribute is "no". Icon index into the icon file. The default inproc handler. May be optionally provided only for Context = LocalServer or LocalServer32. Value of "1" creates a 16-bit InprocHandler (appearing as the InprocHandler value). Value of "2" creates a 32-bit InprocHandler (appearing as the InprocHandler32 value). Value of "3" creates 16-bit as well as 32-bit InprocHandlers. A non-numeric value is treated as a system file that serves as the 32-bit InprocHandler (appearing as the InprocHandler32 value). This column is optional only when the Context column is set to "LocalServer" or "LocalServer32" server context. The text is registered as the argument against the OLE server and is used by OLE for invoking the server. Note that the resolution of properties in the Argument field is limited. A property formatted as [Property] in this field can only be resolved if the property already has the intended value when the component owning the class is installed. For example, for the argument "[#MyDoc.doc]" to resolve to the correct value, the same process must be installing the file MyDoc.doc and the component that owns the class. When the value is "yes", the bare file name can be used for COM servers. The installer registers the file name only instead of the complete path. This enables the server in the current directory to take precedence and allows multiple copies of the same component. Set this value to "yes" in order to create a normal Class table row. Set this value to "no" in order to generate Registry rows that perform similar registration (without the often problematic Windows Installer advertising behavior). Threading model for the CLSID. Version for the CLSID. Specifies the CLSID may be insertable. Specifies the CLSID may be programmable. May only be specified if the value of the Advertise attribute is "no" and Server has not been specified. In addition, it may only be used when the Class element is directly under the Component element. The value can be that of an registry type (REG_SZ). This attribute should be used to specify foreign servers, such as mscoree.dll if needed. May only be specified if the value of the Advertise attribute is "no" and the ForeignServer attribute is not specified. File Id of the COM server file. If this element is nested under a File element, this value defaults to the value of the parent File/@Id. Specifies whether or not to use the short path for the COM server. This can only apply when Advertise is set to 'no'. The default is 'no' meaning that it will use the long file name for the COM server. May only be specified if the value of the Advertise attribute is "no". May only be specified if the value of the Advertise attribute is "no". Set this attribute's value to 'yes' to identify an object as an ActiveX Control. The default value is 'no'. COM Interface registration for parent TypeLib. GUID identifier for COM Interface. Name for COM Interface. Identifies the interface from which the current interface is derived. GUID CLSID for proxy stub to COM Interface. GUID CLSID for 32-bit proxy stub to COM Interface. Number of methods implemented on COM Interface. Determines whether a Typelib version entry should be created with the other COM Interface registry keys. Default is 'yes'. FileType data for class Id registration. Offset into file. If positive, offset is from the beginning; if negative, offset is from the end. Hex value that is AND'd against the bytes in the file at Offset. If the result of the AND'ing of Mask with the bytes in the file is Value, the file is a match for this File Type. Service or group of services that must start before the parent service. The value of this attribute should be one of the following: The name (not the display name) of a previously installed service.The name of a service group (in which case the Group attribute must be set to 'yes'). Set to 'yes' to indicate that the value in the Id attribute is the name of a group of services. Adds services for parent Component. Use the ServiceControl element to remove services. The service executable installed will point to the KeyPath for the Component. Therefore, you must ensure that the correct executable is either the first child File element under this Component or explicitly mark the appropriate File element as KeyPath='yes'. Configures the ACLs for this service. Ordered list of dependencies when installing services. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Unique identifier for this service configuration. This value will default to the Name attribute if not specified.

Determines whether the existing service description will be ignored. If 'yes', the service description will be null, even if the Description attribute is set. Argument used in ServiceControl parent Starts, stops, and removes services for parent Component. This element is used to control the state of a service installed by the MSI or MSM file by using the start, stop and remove attributes. For example, Start='install' Stop='both' Remove='uninstall' would mean: start the service on install, remove the service when the product is uninstalled, and stop the service both on install and uninstall. Ordered list of arguments used when modifying services. Name of the service. Specifies whether the service should be started by the StartServices action on install, uninstall or both. For 'install', the service will be started only when the parent component is being installed (msiInstallStateLocal or msiInstallStateSource); for 'uninstall', the service will be started only when the parent component is being removed (msiInstallStateAbsent); for 'both', the service will be started in both cases.

If this attribute is not present the setting is not configured. This attribute specifies when failure actions should be applied. Allowed values are "failedToStop", "failedToStopOrReturnedError" or a Formatted property that resolves to "1" (for "failedToStopOrReturnedError") or "0" (for "failedToStop"). If this attribute is not present the setting is not configured. This attribute specifies time in milliseconds that the Service Control Manager (SCM) waits after notifying the service of a system shutdown. If this attribute is not present the default value, 3 minutes, is used. Specifies whether to configure the service when the parent Component is installed. This attribute may be combined with OnReinstall and OnUninstall. Specifies whether to configure the service when the parent Component is reinstalled. This attribute may be combined with OnInstall and OnUninstall. Specifies whether to configure the service when the parent Component is uninstalled. This attribute may be combined with OnInstall and OnReinstall. Specifies the name of the service to configure.

Unique identifier for environment entry. Name of the environment variable. The value to set into the environment variable. If this attribute is not set, the environment variable is removed during installation if it exists on the machine. Optional attribute to change the separator used between values. By default a semicolon is used. Specfies whether the environmental variable should be created, set or removed when the parent component is installed. Creates the environment variable if it does not exist, then set it during installation. This has no effect on the value of the environment variable if it already exists. Creates the environment variable if it does not exist, and then set it during installation. If the environment variable exists, set it during the installation. Removes the environment variable during an installation. The installer only removes an environment variable during an installation if the name and value of the variable match the entries in the Name and Value attributes. If you want to remove an environment variable, regardless of its value, do not set the Value attribute. This value is the entire environmental variable. This is the default. This value is prefixed. This value is appended. Specifies that the environment variable should not be removed on uninstall. Specifies that the environment variable should be added to the system environment space. The default is 'no' which indicates the environment variable is added to the user environment space. Conditions for components, controls, features, and products. The condition is specified in the inner text of the element. How To: Block installation based on OS version How To: Check the version number of a file during installation Under a Component element, the condition becomes the condition of the component. Under a Control element, the condition becomes a ControlCondition entry. Under a Feature element, the condition becomes a Condition entry. Under a Fragment or Product element, the condition becomes a LaunchCondition entry. Used only under Control elements and is required. Allows specific actions to be applied to a control based on the result of this condition. Set the Control as the default. Only used under Control elements. Enable the Control. Only used under Control elements. Disable the Control. Only used under Control elements. Hide the Control. Only used under Control elements. Display the Control. Only used under Control elements.

If this attribute is not set, it will default to the directory of parent component. The number of bytes of disk space to reserve if the component is installed to run from source. The number of bytes of disk space to reserve if the component is installed to run locally. Component for parent Directory How To: Add a file to your installer Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Component identifier; this is the primary key for identifying components. If omitted, the compiler defaults the identifier to the identifier of the resource that is the explicit keypath of the component (for example, a child File element with KeyPath attribute with value 'yes'. Set this attribute to create a ComPlus entry. The value should be the export flags used during the generation of the .msi file. For more information see the COM+ documentation in the Platform SDK. Set this attribute to 'yes' in order to disable registry reflection on all existing and new registry keys affected by this component. When set to 'yes', the Windows Installer calls the RegDisableReflectionKey on each key being accessed by the component. This bit is available with Windows Installer version 4.0 and is ignored on 32-bit systems. Sets the Directory of the Component. If this element is nested under a Directory element, this value defaults to the value of the parent Directory/@Id. This attribute provides a default DiskId attribute for all child File elements. Specifying the DiskId on a Component element will override any DiskId attributes set by parent Directory or DirectoryRef elements. See the File element's DiskId attribute for more information about the purpose of the DiskId. Identifies a feature to which this component belongs, as a shorthand for a child ComponentRef element of the Feature element. The value of this attribute should correspond to the Id attribute of a Feature element authored elsewhere. Note that a single component can belong to multiple features but this attribute allows you to specify only a single feature. This value should be a guid that uniquely identifies this component's contents, language, platform, and version. If omitted, the default value is '*' which indicates that the linker should generate a stable guid. Generatable guids are supported only for components with a single file as the component's keypath or no files and a registry value as the keypath. It's also possible to set the value to an empty string to specify an unmanaged component. Unmanaged components are a security vulnerability because the component cannot be removed or repaired by Windows Installer (it is essentially an unpatchable, permanent component). Therefore, a guid should always be specified for any component which contains resources that may need to be patched in the future. If this attribute's value is set to 'yes', then the Directory of this Component is used as the KeyPath. To set a Registry value or File as the KeyPath of a component, set the KeyPath attribute to 'yes' on one of those child elements. If KeyPath is not set to 'yes' for the Component or for a child Registry value or File, WiX will look at the child elements under the Component in sequential order and try to automatically select one of them as a key path. Allowing WiX to automatically select a key path can be dangerous because adding or removing child elements under the Component can inadvertantly cause the key path to change, which can lead to installation problems. Optional value that specifies the location that the component can be run from. Prevents the component from running from the source or the network (this is the default behavior if this attribute is not set). Enforces that the component can only be run from the source (it cannot be run from the user's computer). Allows the component to run from source or locally. If this attribute is set to 'yes', a new Component/@Guid will be generated for each instance transform. Ensure that all of the resources contained in a multi-instance Component will be installed to different paths based on the instance Property; otherwise, the Component Rules will be violated. If this attribute is set to 'yes', the installer does not install or reinstall the component if a key path file or a key path registry entry for the component already exists. The application does register itself as a client of the component. Use this flag only for components that are being registered by the Registry table. Do not use this flag for components registered by the AppId, Class, Extension, ProgId, MIME, and Verb tables. If this attribute is set to 'yes', the installer does not remove the component during an uninstall. The installer registers an extra system client for the component in the Windows Installer registry settings (which basically just means that at least one product is always referencing this component). Note that this option differs from the behavior of not setting a guid because although the component is permanent, it is still patchable (because Windows Installer still tracks it), it's just not uninstallable. If this attribute's value is set to 'yes', enables advanced patching semantics for Components that are shared across multiple Products. Specifically, the Windows Installer will cache the shared files to improve patch uninstall. This functionality is available in Windows Installer 4.5 and later. If this attribute's value is set to 'yes', the installer increments the reference count in the shared DLL registry of the component's key file. If this bit is not set, the installer increments the reference count only if the reference count already exists. If this attribute is set to 'yes', the installer reevaluates the value of the statement in the Condition upon a reinstall. If the value was previously False and has changed to True, the installer installs the component. If the value was previously True and has changed to False, the installer removes the component even if the component has other products as clients. If this attribute is set to 'yes', the installer will uninstall the Component's files and registry keys when it is superseded by a patch. This functionality is available in Windows Installer 4.5 and later. Set this attribute to 'yes' to mark this as a 64-bit component. This attribute facilitates the installation of packages that include both 32-bit and 64-bit components. If this is a 64-bit component replacing a 32-bit component, set this attribute to 'yes' and assign a new GUID in the Guid attribute. The default value is based on the platform set by the -arch switch to candle.exe or the InstallerPlatform property in a .wixproj MSBuild project: For x86 and ARM, the default value is 'no'. For x64 and IA64, the default value is 'yes'. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Groups together multiple components to be used in other locations. Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Identifier for the ComponentGroup. Sets the default directory identifier for child Component elements. Used to set the default file system source for child Component elements. For more information, see Specifying source files. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Create a reference to a ComponentGroup in another Fragment. The identifier of the ComponentGroup to reference. Set this attribute to 'yes' in order to make the parent feature of this component the primary feature for this component. Components may belong to multiple features. By designating a feature as the primary feature of a component, you ensure that whenever a component is selected for install-on-demand (IOD), the primary feature will be the one to install it. This attribute should only be set if a component actually nests under multiple features. If a component nests under only one feature, that feature is the primary feature for the component. You cannot set more than one feature as the primary feature of a given component. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Used only for PatchFamilies to include all changes between the baseline and upgraded packages in a patch. Warning: this is intended for testing purposes only. Shipping a patch with all changes negates the benefits of using patch families for including only specific changes. Because changing the ProductCode is not supported in a patch, the ProductCode property is automatically removed from the transform. Used only for PatchFamilies to include only a binary table entry in a patch. The identifier of the Binary element to reference. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Used only for PatchFamilies to include only a icon table entry in a patch. The identifier of the Icon element to reference. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Create a reference to a Feature element in another Fragment. How To: Add a file to your installer The identifier of the Component element to reference. Set this attribute to 'yes' in order to make the parent feature of this component the primary feature for this component. Components may belong to multiple features. By designating a feature as the primary feature of a component, you ensure that whenever a component is selected for install-on-demand (IOD), the primary feature will be the one to install it. This attribute should only be set if a component actually nests under multiple features. If a component nests under only one feature, that feature is the primary feature for the component. You cannot set more than one feature as the primary feature of a given component. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. How To: Install the Visual C++ Redistributable with your installer Merge directive to bring in a merge module that will be redirected to the parent directory. Data to use as input to a configurable merge module. The unique identifier for the Merge element in the source code. Referenced by the MergeRef/@Id. The value of this attribute should correspond to the Id attribute of a Media element authored elsewhere. By creating this connection between the merge module and Media element, you set the packaging options to the values specified in the Media element (values such as compression level, cab embedding, etc...). Specifies if the files in the merge module should be compressed. Specifies the decimal LCID or localization token for the language to merge the Module in as. Path to the source location of the merge module. How To: Install the Visual C++ Redistributable with your installer Merge reference to connect a Merge Module to parent Feature The unique identifier for the Merge element to be referenced. Specifies whether the feature containing this MergeRef is the primary feature for advertising the merge module's components. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Data to use as input to a configurable merge module. Name of the item in the ModuleConfiguration table. Value to be passed to configurable merge module. Directory layout for the product. Also specifies the mappings between source and target directories. How To: Add a file to your installer Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. This value is the unique identifier of the directory entry. The Component Guid Generation Seed is a guid that must be used when a Component with the generate guid directive ("*") is not rooted in a standard Windows Installer directory (for example, ProgramFilesFolder or CommonFilesFolder). It is recommended that this attribute be avoided and that developers install their Components under standard directories with unique names instead (for example, "ProgramFilesFolder\Company Name Product Name Version"). It is important to note that once a directory is assigned a Component Guid Generation Seed the value must not change until (and must be changed when) the path to that directory, including itself and all parent directories, changes. Sets the default disk identifier for the files contained in this directory. This attribute's value may be overridden by a child Component, Directory, Merge or File element. See the File or Merge elements' DiskId attribute for more information. Used to set the file system source for this directory's child elements. For more information, see Specifying source files. The name of the directory. Do not specify this attribute (or the LongName attribute) if this directory represents the same directory as the parent (see the Windows Installer SDK's Directory table topic for more information about the "." operator). In prior versions of the WiX toolset, this attribute specified the short directory name. This attribute's value may now be either a short or long directory name. If a short directory name is specified, the ShortName attribute may not be specified. If a long directory name is specified, the LongName attribute may not be specified. Also, if this value is a long directory name, the ShortName attribute may be omitted to allow WiX to attempt to generate a unique short directory name. However, if this name collides with another directory or you wish to manually specify the short directory name, then the ShortName attribute may be specified. The short name of the directory in 8.3 format. This attribute should only be set if there is a conflict between generated short directory names or the user wants to manually specify the short directory name. The short name of the directory on the source media in 8.3 format. This attribute should only be set if there is a conflict between generated short directory names or the user wants to manually specify the short source directory name. The name of the directory on the source media. If this attribute is not specified, Windows Installer will default to the Name attribute. In prior versions of the WiX toolset, this attribute specified the short source directory name. This attribute's value may now be either a short or long directory name. If a short directory name is specified, the ShortSourceName attribute may not be specified. If a long directory name is specified, the LongSource attribute may not be specified. Also, if this value is a long directory name, the ShortSourceName attribute may be omitted to allow WiX to attempt to generate a unique short directory name. However, if this name collides with another directory or you wish to manually specify the short directory name, then the ShortSourceName attribute may be specified.

Used to set the file system source for this DirectoryRef's child elements. For more information, see Specifying source files. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Specifies the lower bound on the range of product versions to be detected by FindRelatedProducts. Specifies the upper boundary of the range of product versions detected by FindRelatedProducts. Specifies the set of languages detected by FindRelatedProducts. Enter a list of numeric language identifiers (LANGID) separated by commas (,). Leave this value null to specify all languages. Set ExcludeLanguages to "yes" in order detect all languages, excluding the languages listed in this value. The installer sets the REMOVE property to features specified in this column. The features to be removed can be determined at run time. The Formatted string entered in this field must evaluate to a comma-delimited list of feature names. For example: [Feature1],[Feature2],[Feature3]. No features are removed if the field contains formatted text that evaluates to an empty string. The installer sets REMOVE=ALL only if the Remove field is empty. When the FindRelatedProducts action detects a related product installed on the system, it appends the product code to the property specified in this field. Windows Installer documentation for the Upgrade table states that the property specified in this field must be a public property and must be added to the SecureCustomProperties property. WiX automatically appends the property specified in this field to the SecureCustomProperties property when creating an MSI. Each UpgradeVersion must have a unique Property value. After the FindRelatedProducts action is run, the value of this property is a list of product codes, separated by semicolons (;), detected on the system. Set to "yes" to migrate feature states from upgraded products by enabling the logic in the MigrateFeatureStates action. Set to "yes" to detect products and applications but do not uninstall. Set to "yes" to continue installation upon failure to remove a product or application. Set to "no" to make the range of versions detected exclude the value specified in Minimum. This attribute is "yes" by default. Set to "yes" to make the range of versions detected include the value specified in Maximum. Set to "yes" to detect all languages, excluding the languages listed in the Language attribute. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Upgrade info for a particular UpgradeCode Nesting a Property element under an Upgrade element has been deprecated. Please nest Property elements in any of the other supported locations. This value specifies the upgrade code for the products that are to be detected by the FindRelatedProducts action. A feature for the Feature table. Features are the smallest installable unit. See msi.chm for more detailed information on the myriad installation options for a feature. How To: Add a file to your installer Extensibility point in the WiX XML Schema. Schema extensions can register additional elements at this point in the schema. Unique identifier of the feature. This attribute determines if a user will have the option to set a feature to absent in the user interface. Allows the user interface to display an option to change the feature state to Absent. Prevents the user interface from displaying an option to change the feature state to Absent by setting the msidbFeatureAttributesUIDisallowAbsent attribute. This will force the feature to the installation state, whether or not the feature is visible in the UI. This attribute determines the possible advertise states for this feature. Prevents this feature from being advertised by setting the msidbFeatureAttributesDisallowAdvertise attribute. Prevents advertising for this feature if the operating system shell does not support Windows Installer descriptors by setting the msidbFeatureAttributesNoUnsupportedAdvertise attribute. Allows the feature to be advertised. Specify the Id of a Directory that can be configured by the user at installation time. This identifier must be a public property and therefore completely uppercase. Longer string of text describing the feature. This localizable string is displayed by the Text Control of the Selection Dialog. Determines the initial display of this feature in the feature tree. This attribute's value should be one of the following: collapseInitially shows the feature collapsed. This is the default value.expandInitially shows the feature expanded.hiddenPrevents the feature from displaying in the user interface.<an explicit integer value> For advanced users only, it is possible to directly set the integer value of the display value that will appear in the Feature row. This attribute determines the default install/run location of a feature. This attribute cannot be specified if the value of the FollowParent attribute is 'yes' since that would ask the installer to force this feature to follow the parent installation state and simultaneously favor a particular installation state just for this feature. Forces the feature to follow the same installation state as its parent feature. Favors installing this feature locally by setting the msidbFeatureAttributesFavorLocal attribute. Favors running this feature from source by setting the msidbFeatureAttributesFavorSource attribute. Sets the install level of this feature. A value of 0 will disable the feature. Processing the Condition Table can modify the level value (this is set via the Condition child element). The default value is "1". Short string of text identifying the feature. This string is listed as an item by the SelectionTree control of the Selection Dialog. This attribute determines the default advertise state of the feature. Sets the feature to be advertised by setting the msidbFeatureAttributesFavorAdvertise attribute. This value cannot be set if the value of the AllowAdvertise attribute is 'no' since that would ask the installer to disallow the advertised state for this feature while at the same time favoring it. Sets the feature to the default non-advertised installation option. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema.

Schema extensions can register additional attributes at this point in the schema. Create a reference to a FeatureGroup in another Fragment. The identifier of the FeatureGroup to reference. Normally feature group references that end up nested under a parent element create a connection to that parent. This behavior is undesirable when trying to simply reference to a FeatureGroup in a different Fragment. Specify 'yes' to have this feature group reference not create a connection to its parent. The default is 'no'. Set this attribute to 'yes' in order to make the parent feature of this group the primary feature for any components and merges contained in the group. Features may belong to multiple features. By designating a feature as the primary feature of a component or merge, you ensure that whenever a component is selected for install-on-demand (IOD), the primary feature will be the one to install it. This attribute should only be set if a component actually nests under multiple features. If a component nests under only one feature, that feature is the primary feature for the component. You cannot set more than one feature as the primary feature of a given component. Extensibility point in the WiX XML Schema.

This number must be equal to or greater than 1. The name of the cabinet if some or all of the files stored on the media are in a cabinet file. If no cabinets are used, this attribute must not be set. Indicates the compression level for the Media's cabinet. This attribute can only be used in conjunction with the Cabinet attribute. The default is 'mszip'. The disk name, which is usually the visible text printed on the disk. This localizable text is used to prompt the user when this disk needs to be inserted. This value will be used in the "[1]" of the DiskPrompt Property. Using this attribute will require you to define a DiskPrompt Property. Instructs the binder to embed the cabinet in the product if 'yes'. This attribute can only be specified in conjunction with the Cabinet attribute. This attribute specifies the root directory for the uncompressed files that are a part of this Media element. By default, the src will be the output directory for the final image. The default value ensures the binder generates an installable image. If a relative path is specified in the src attribute, the value will be appended to the image's output directory. If an absolute path is provided, that path will be used without modification. The latter two options are provided to ease the layout of an image onto multiple medias (CDs/DVDs). The label attributed to the volume. This is the volume label returned by the GetVolumeInformation function. If the SourceDir property refers to a removable (floppy or CD-ROM) volume, then this volume label is used to verify that the proper disk is in the drive before attempting to install files. The entry in this column must match the volume label of the physical media. Optional property that identifies the source of the embedded cabinet. If a cabinet is specified for a patch, this property should be defined and unique to each patch so that the embedded cabinet containing patched and new files can be located in the patch package. If the cabinet is not embedded - this is not typical - the cabinet can be found in the directory referenced in this column. If empty, the external cabinet must be located in the SourceDir directory. MediaTeplate element describes information to automatically assign files to cabinets. A maximumum number of cabinets created is 999. Templated name of the cabinet if some or all of the files stored on the media are in a cabinet file. This name must begin with either a letter or an underscore, contain maximum of five characters and {0} in the cabinet name part and must end three character extension. The default is cab{0}.cab. Indicates the compression level for the Media's cabinet. This attribute can only be used in conjunction with the Cabinet attribute. The default is 'mszip'. The disk name, which is usually the visible text printed on the disk. This localizable text is used to prompt the user when this disk needs to be inserted. This value will be used in the "[1]" of the DiskPrompt Property. Using this attribute will require you to define a DiskPrompt Property. Instructs the binder to embed the cabinets in the product if 'yes'. The label attributed to the volume. This is the volume label returned by the GetVolumeInformation function. If the SourceDir property refers to a removable (floppy or CD-ROM) volume, then this volume label is used to verify that the proper disk is in the drive before attempting to install files. The entry in this column must match the volume label of the physical media. Size of uncompressed files in each cabinet, in megabytes. WIX_MUMS environment variable can be used to override this value. Default value is 200 MB. Maximum size of cabinet files in megabytes for large files. This attribute is used for packaging files that are larger than MaximumUncompressedMediaSize into smaller cabinets. If cabinet size exceed this value, then setting this attribute will cause the file to be split into multiple cabinets of this maximum size. For simply controlling cabinet size without file splitting use MaximumUncompressedMediaSize attribute. Setting this attribute will disable smart cabbing feature for this Fragment / Product. Setting WIX_MCSLFS environment variable can be used to override this value. Minimum allowed value of this attribute is 20 MB. Maximum allowed value and the Default value of this attribute is 2048 MB (2 GB). This element has been deprecated. Use the Binary/@SuppressModularization, CustomAction/@SuppressModularization, or Property/@SuppressModularization attributes instead. The name of the item to ignore modularization for. The type of the item to ignore modularization for. Specifies a custom action to be added to the MSI CustomAction table. Various combinations of the attributes for this element correspond to different custom action types. For more information about custom actions see the Custom Action Types topic on MSDN. The text node is only valid if the Script attribute is specified. In that case, the text node contains the script to embed. The identifier of the custom action. This attribute is a reference to a Binary element with matching Id attribute. That binary stream contains the custom action for use during install. The custom action will not be installed into a target directory. This attribute is typically used with the DllEntry attribute to specify the custom action DLL to use for a type 1 custom action, with the ExeCommand attribute to specify a type 17 custom action that runs an embedded executable, or with the VBScriptCall or JScriptCall attributes to specify a type 5 or 6 custom action. This attribute specifies a reference to a File element with matching Id attribute that will execute the custom action code in the file after the file is installed. This attribute is typically used with the ExeCommand attribute to specify a type 18 custom action that runs an installed executable, with the DllEntry attribute to specify an installed custom action DLL to use for a type 17 custom action, or with the VBScriptCall or JScriptCall attributes to specify a type 21 or 22 custom action. This attribute specifies a reference to a Property element with matching Id attribute that specifies the Property to be used or updated on execution of this custom action. This attribute is typically used with the Value attribute to create a type 51 custom action that parses the text in Value and places it into the specified Property. This attribute is also used with the ExeCommand attribute to create a type 50 custom action that uses the value of the given property to specify the path to the executable. Type 51 custom actions are often useful to pass values to a deferred custom action. See http://msdn.microsoft.com/library/aa370543.aspx for more information. This attribute specifies a reference to a Directory element with matching Id attribute containing a directory path. This attribute is typically used with the ExeCommand attribute to specify the source executable for a type 34 custom action, or with the Value attribute to specify a formatted string to place in the specified Directory table entry in a type 35 custom action. This attribute specifies the name of a function in a custom action to execute. This attribute is used with the BinaryKey attribute to create a type 1 custom action, or with the FileKey attribute to create a type 17 custom action. This attribute specifies the command line parameters to supply to an externally run executable. This attribute is typically used with the BinaryKey attribute for a type 2 custom action, the FileKey attribute for a type 18 custom action, the Property attribute for a type 50 custom action, or the Directory attribute for a type 34 custom action that specify the executable to run. This attribute specifies the name of the JScript function to execute in a script. The script must be provided in a Binary element identified by the BinaryKey attribute described above. In other words, this attribute must be specified in conjunction with the BinaryKey attribute. This attribute specifies the name of the VBScript Subroutine to execute in a script. The script must be provided in a Binary element identified by the BinaryKey attribute described above. In other words, this attribute must be specified in conjunction with the BinaryKey attribute. Creates a type 37 or 38 custom action. The text of the element should contain the script to be embedded in the package. Use to suppress modularization of this custom action name in merge modules. This should only be necessary for table-driven custom actions because the table name which they interact with cannot be modularized, so there can only be one instance of the table. This attribute specifies a string value to use in the custom action. This attribute must be used with the Property attribute to set the property as part of a type 51 custom action or with the Directory attribute to set a directory path in that table in a type 35 custom action. The value can be a literal value or derived from a Property element using the Formatted syntax. This attribute specifies an index in the MSI Error table to use as an error message for a type 19 custom action that displays the error message and aborts a product's installation. Set this attribute to set the return behavior of the custom action. Indicates that the custom action will run asyncronously and execution may continue after the installer terminates. Indicates that the custom action will run asynchronously but the installer will wait for the return code at sequence end. Indicates that the custom action will run synchronously and the return code will be checked for success. This is the default. Indicates that the custom action will run synchronously and the return code will not be checked. This attribute indicates the scheduling of the custom action. Indicates that the custom action will run after successful completion of the installation script (at the end of the installation). Indicates that the custom action runs in-script (possibly with elevated privileges). Indicates that the custom action will only run in the first sequence that runs it. Indicates that the custom action will run during normal processing time with user privileges. This is the default. Indicates that the custom action will only run in the first sequence that runs it in the same process. Indicates that a custom action will run in the rollback sequence when a failure occurs during installation, usually to undo changes made by a deferred custom action. Indicates that a custom action should be run a second time if it was previously run in an earlier sequence. This attribute specifies whether the Windows Installer, which executes as LocalSystem, should impersonate the user context of the installing user when executing this custom action. Typically the value should be 'yes', except when the custom action needs elevated privileges to apply changes to the machine. This attribute specifies that the Windows Installer, execute the custom action only when a patch is being uninstalled. These custom actions should also be conditioned using the MSIPATCHREMOVE property to ensure proper down level (less than Windows Installer 4.5) behavior. Specifies that a script custom action targets a 64-bit platform. Valid only when used with the Script, VBScriptCall, and JScriptCall attributes. The default value is based on the platform set by the -arch switch to candle.exe or the InstallerPlatform property in a .wixproj MSBuild project: For x86 and ARM, the default value is 'no'. For x64 and IA64, the default value is 'yes'. This attribute specifies controls whether the custom action will impersonate the installing user during per-machine installs on Terminal Server machines. Deferred execution custom actions that do not specify this attribute, or explicitly set it 'no', will run with no user impersonation on Terminal Server machines during per-machine installations. This attribute is only applicable when installing on the Windows Server 2003 family. Ensures the installer does not log the CustomActionData for the deferred custom action. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema.

Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Sets a Directory to a particular value. This is accomplished by creating a Type 51 custom action that is appropriately scheduled in the InstallUISequence and InstallExecuteSequence. The condition that determines whether the Directory is set. If the condition evaluates to false, the SetDirectory is skipped. By default the action is "Set" + Id attribute's value. This optional attribute can override the action name in the case where multiple SetDirectory elements target the same Id (probably with mutually exclusive conditions). This attribute specifies a reference to a Directory element with matching Id attribute. The path of the Directory will be set to the Value attribute. Controls which sequences the Directory assignment is sequenced in. For 'execute', the assignment is scheduled in the InstallExecuteSequence. For 'ui', the assignment is scheduled in the InstallUISequence. For 'first', the assignment is scheduled in the InstallUISequence or the InstallExecuteSequence if the InstallUISequence is skipped at install time. For 'both', the assignment is scheduled in both the InstallUISequence and the InstallExecuteSequence. The default is 'both'. This attribute specifies a string value to assign to the Directory. The value can be a literal value or derived from a Property element using the Formatted syntax. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Sets a Property to a particular value. This is accomplished by creating a Type 51 custom action that is appropriately scheduled in the InstallUISequence and InstallExecuteSequence. The condition that determines whether the Property is set. If the condition evaluates to false, the Set is skipped. By default the action is "Set" + Id attribute's value. This optional attribute can override the action name in the case where multiple SetProperty elements target the same Id (probably with mutually exclusive conditions). The name of the standard or custom action after which this action should be performed. Mutually exclusive with the Before attribute. A Before or After attribute is required when setting a Property. The name of the standard or custom action before which this action should be performed. Mutually exclusive with the After attribute. A Before or After attribute is required when setting a Property. This attribute specifies the Property to set to the Value. Controls which sequences the Property assignment is sequenced in. For 'execute', the assignment is scheduled in the InstallExecuteSequence. For 'ui', the assignment is scheduled in the InstallUISequence. For 'first', the assignment is scheduled in the InstallUISequence or the InstallExecuteSequence if the InstallUISequence is skipped at install time. For 'both', the assignment is scheduled in both the InstallUISequence and the InstallExecuteSequence. The default is 'both'. This attribute specifies a string value to assign to the Property. The value can be a literal value or derived from a Property element using the Formatted syntax. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. This will cause the entire contents of the Fragment containing the referenced PatchFamily to be used in the process of creating a patch. The identifier of the PatchFamily to reference. Specifies the ProductCode of the product that this family applies to. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Sets the ProductID property to the full product identifier. This action must be sequenced before the user interface wizard in the InstallUISequence table and before the RegisterUser action in the InstallExecuteSequence table. If the product identifier has already been validated successfully, the ValidateProductID action does nothing. The ValidateProductID action always returns a success, whether or not the product identifier is valid, so that the product identifier can be entered on the command line the first time the product is run. The product identifier can be validated without having the user reenter this information by setting the PIDKEY property on the command line or by using a transform. The display of the dialog box requesting the user to enter the product identifier can then be made conditional upon the presence of the ProductID property, which is set when the PIDKEY property is validated. The condition for this action may be specified in the element's inner text. Initiates the internal installation costing process. Any standard or custom actions that affect costing should be sequenced before the CostInitialize action. Call the FileCost action immediately following the CostInitialize action. Then call the CostFinalize action following the CostInitialize action to make all final cost calculations available to the installer through the Component table. The condition for this action may be specified in the element's inner text. Initiates dynamic costing of standard installation actions. Any standard or custom actions that affect costing should sequenced before the CostInitialize action. Call the FileCost action immediately following the CostInitialize action. Then call the CostFinalize action following the FileCost action to make all final cost calculations available to the installer through the Component table. The CostInitialize action must be executed before the FileCost action. The installer then determines the disk-space cost of every file in the File table, on a per-component basis, taking both volume clustering and the presence of existing files that may need to be overwritten into account. All actions that consume or release disk space are also considered. If an existing file is found, a file version check is performed to determine whether the new file actually needs to be installed or not. If the existing file is of an equal or greater version number, the existing file is not overwritten and no disk-space cost is incurred. In all cases, the installer uses the results of version number checking to set the installation state of each file. The FileCost action initializes cost calculation with the installer. Actual dynamic costing does not occur until the CostFinalize action is executed. The condition for this action may be specified in the element's inner text. Installs a copy of a component (commonly a shared DLL) into a private location for use by a specific application (typically an .exe). This isolates the application from other copies of the component that may be installed to a shared location on the computer. The action refers to each record of the IsolatedComponent table and associates the files of the component listed in the Component_Shared field with the component listed in the Component_Application field. The installer installs the files of Component_Shared into the same directory as Component_Application. The installer generates a file in this directory, zero bytes in length, having the short filename name of the key file for Component_Application (typically this is the same file name as the .exe) appended with .local. The IsolatedComponent action does not affect the installation of Component_Application. Uninstalling Component_Application also removes the Component_Shared files and the .local file from the directory. The IsolateComponents action can be used only in the InstallUISequence table and the InstallExecuteSequence table. This action must come after the CostInitialize action and before the CostFinalize action. The condition for this action may be specified in the element's inner text. Ends the internal installation costing process begun by the CostInitialize action. Any standard or custom actions that affect costing should be sequenced before the CostInitialize action. Call the FileCost action immediately following the CostInitialize action and then call the CostFinalize action to make all final cost calculations available to the installer through the Component table. The CostFinalize action must be executed before starting any user interface sequence which allows the user to view or modify Feature table selections or directories. The CostFinalize action queries the Condition table to determine which features are scheduled to be installed. Costing is done for each component in the Component table. The CostFinalize action also verifies that all the target directories are writable before allowing the installation to continue. The condition for this action may be specified in the element's inner text. Checks for existing ODBC drivers and sets the target directory for each new driver to the location of an existing driver.

The AppSearch action may use this information to determine where upgrades are to be installed. The AppSearch action can also be used to set a property to the existing value of an registry or .ini file entry. AppSearch should be authored into the InstallUISequence table and InstallExecuteSequence table. The installer prevents The AppSearch action from running in the InstallExecuteSequence sequence if the action has already run in InstallUISequence sequence.

The element value is the optional Condition expression. The parent Control for this Publish element, should only be specified when this element is a child of the UI element. The parent Dialog for this Publish element, should only be specified when this element is a child of the UI element. This attribute will create a reference to the specified Dialog, so an additional DialogRef is not necessary. Set this attribute's value to one of the standard control events to trigger that event. Either this attribute or the Property attribute must be set, but not both at the same time. This attribute should only need to be set if this element is nested under a UI element in order to control the order in which this publish event will be started. If this element is nested under a Control element, the default value will be one greater than any previous Publish element's order (the first element's default value is 1).

Semi-colon list of keys, all of which need to be modularized. Row data for a Custom Table Used for a Custom Table. Specifies the data for the parent Row and specified Column. A data value Specifies in which column to insert this data. Use this element to ensure that a table appears in the installer database, even if its empty. This element is particularly useful for two problems that may occur while merging merge modules: The first likely problem is that in order to properly merge you need to have certain tables present prior to merging. Using this element is one way to ensure those tables are present prior to the merging. The other common problem is that a merge module has incorrect validation information about some tables. By ensuring these tables prior to merging, you can avoid this problem because the correct validation information will go into the installer database before the merge module has a chance to set it incorrectly. The name of the table. This element exposes advanced WiX functionality. Use this element to declare WiX variables from directly within your authoring. WiX variables are not resolved until the final msi/msm/pcp file is actually generated. WiX variables do not persist into the msi/msm/pcp file, so they cannot be used when an MSI file is being installed; it's a WiX-only concept. The name of the variable. Set this value to 'yes' in order to make the variable's value overridable either by another WixVariable entry or via the command-line option -d<name>=<value> for light.exe. If the same variable is declared overridable in multiple places it will cause an error (since WiX won't know which value is correct). The default value is 'no'. The value of the variable. The value cannot be an empty string because that would make it possible to accidentally set a column to null. Use this element to contain definitions for instance transforms. The Id of the Property who's value should change for each instance. Defines an instance transform for your product. The identity of the instance transform. This value will define the name by which the instance should be referred to on the command line. In addition, the value of the this attribute will determine what the value of the property specified in Property attribute on InstanceTransforms will change to for each instance. The ProductCode for this instance. The ProductName for this instance. The UpgradeCode for this instance. Simplifies authoring for major upgrades, including support for preventing downgrades. The parent Product element must have valid UpgradeCode and Version attributes. When the FindRelatedProducts action detects a related product installed on the system, it appends the product code to the property named WIX_UPGRADE_DETECTED. After the FindRelatedProducts action is run, the value of the WIX_UPGRADE_DETECTED property is a list of product codes, separated by semicolons (;), detected on the system. When set to no (the default), products with lower version numbers are blocked from installing when a product with a higher version is installed; the DowngradeErrorMessage attribute must also be specified. When set to yes, any version can be installed over any other version. When set to no (the default), installing a product with the same version and upgrade code (but different product code) is allowed and treated by MSI as two products. When set to yes, WiX sets the msidbUpgradeAttributesVersionMaxInclusive attribute, which tells MSI to treat a product with the same version as a major upgrade. This is useful when two product versions differ only in the fourth version field. MSI specifically ignores that field when comparing product versions, so two products that differ only in the fourth version field are the same product and need this attribute set to yes to be detected. Note that because MSI ignores the fourth product version field, setting this attribute to yes also allows downgrades when the first three product version fields are identical. For example, product version 1.0.0.1 will "upgrade" 1.0.0.2998 because they're seen as the same version (1.0.0). That could reintroduce serious bugs so the safest choice is to change the first three version fields and omit this attribute to get the default of no. This attribute cannot be "yes" when AllowDowngrades is also "yes" -- AllowDowngrades already allows two products with the same version number to upgrade each other. When set to yes, products with higer version numbers are blocked from installing when a product with a lower version is installed; the UpgradeErrorMessage attribute must also be specified. When set to no (the default), any version can be installed over any lower version. The message displayed if users try to install a product with a lower version number when a product with a higher version is installed. Used only when AllowDowngrades is no (the default). The message displayed if users try to install a product with a higer version number when a product with a lower version is installed. Used only when Disallow is yes. When set to yes (the default), the MigrateFeatureStates standard action will set the feature states of the upgrade product to those of the installed product. When set to no, the installed features have no effect on the upgrade installation. When set to yes, failures removing the installed product during the upgrade will be ignored. When set to no (the default), failures removing the installed product during the upgrade will be considered a failure and, depending on the scheduling, roll back the upgrade. A formatted string that contains the list of features to remove from the installed product. The default is to remove all features. Note that if you use formatted property values that evaluate to an empty string, no features will be removed; only omitting this attribute defaults to removing all features. Determines the scheduling of the RemoveExistingProducts standard action, which is when the installed product is removed. The default is "afterInstallValidate" which removes the installed product entirely before installing the upgrade product. It's slowest but gives the most flexibility in changing components and features in the upgrade product. For more information, see RemoveExistingProducts. (Default) Schedules RemoveExistingProducts after the InstallValidate standard action. This scheduling removes the installed product entirely before installing the upgrade product. It's slowest but gives the most flexibility in changing components and features in the upgrade product. Note that if the installation of the upgrade product fails, the machine will have neither version installed. Schedules RemoveExistingProducts after the InstallInitialize standard action. This is similar to the afterInstallValidate scheduling, but if the installation of the upgrade product fails, Windows Installer also rolls back the removal of the installed product -- in other words, reinstalls it. Schedules RemoveExistingProducts between the InstallExecute and InstallFinalize standard actions. This scheduling installs the upgrade product "on top of" the installed product then lets RemoveExistingProducts uninstall any components that don't also exist in the upgrade product. Note that this scheduling requires strict adherence to the component rules because it relies on component reference counts to be accurate during installation of the upgrade product and removal of the installed product. For more information, see Bob Arnson's blog post "Paying for Upgrades" for details. If installation of the upgrade product fails, Windows Installer also rolls back the removal of the installed product -- in other words, reinstalls it. Schedules RemoveExistingProducts between the InstallExecuteAgain and InstallFinalize standard actions. This is identical to the afterInstallExecute scheduling but after the InstallExecuteAgain standard action instead of InstallExecute. Schedules RemoveExistingProducts after the InstallFinalize standard action. This is similar to the afterInstallExecute and afterInstallExecuteAgain schedulings but takes place outside the installation transaction so if installation of the upgrade product fails, Windows Installer does not roll back the removal of the installed product, so the machine will have both versions installed. Specifies the lower bound on the range of product versions to be detected by FindRelatedProducts. Specifies the upper boundary of the range of product versions detected by FindRelatedProducts. Specifies the set of languages detected by FindRelatedProducts. Enter a list of numeric language identifiers (LANGID) separated by commas (,). Leave this value null to specify all languages. Set ExcludeLanguages to "yes" in order detect all languages, excluding the languages listed in this value. Set to "no" to make the range of versions detected exclude the value specified in Minimum. This attribute is "yes" by default. Set to "yes" to make the range of versions detected include the value specified in Maximum. Set to "yes" to detect all languages, excluding the languages listed in the Language attribute. This value specifies the upgrade code for the products that are to be detected by the FindRelatedProducts action. Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. Text node specifies the condition of the action. The name of an action that this action should come after.

A per-machine installation will make the operation occur under HKEY_LOCAL_MACHINE. Operation occurs under HKEY_CLASSES_ROOT. When using Windows 2000 or later, the installer writes or removes the value from the HKCU\Software\Classes hive during per-user installations. When using Windows 2000 or later operating systems, the installer writes or removes the value from the HKLM\Software\Classes hive during per-machine installations. Operation occurs under HKEY_CURRENT_USER. It is recommended to set the KeyPath='yes' attribute when setting this value for writing values in order to ensure that the installer writes the necessary registry entries when there are multiple users on the same computer. Operation occurs under HKEY_LOCAL_MACHINE. Operation occurs under HKEY_USERS. Value indicates that this action is executed if the installer returns the associated exit type. Each exit type can be used with no more than one action. Multiple actions can have exit types assigned, but every action and exit type must be different. Exit types are typically used with dialog boxes. Specifies whether an action occur on install, uninstall or both.
