How To: Create an Uninstall Shortcut

When installing an application it is a common requirement to place a shortcut on the user's Start Menu to provide a method of uninstalling the application. This how to demonstrates the steps required to create an uninstall shortcut on the start menu that passes all ICE validation checks.

This how to assumes you are starting with the sample described the How To: Create a Shortcut on the Start Menu topic.

Step 1: Add the Uninstall Shortcut

The <Shortcut> element is used to add the uninstall shortcut to the start menu, and the shortcut points to msiexec.exe (the Windows Installer executable used to actually invoke the uninstall process). Anywhere within the existing ApplicationShortcut component add the following:

<Shortcut Id="UninstallProduct"             
          Name="Uninstall My Application"
          Target="[System64Folder]msiexec.exe"
          Arguments="/x [ProductCode]"
          Description="Uninstalls My Application" />

The Target attribute points to the location of msiexec.exe. The Windows Installer System64Folder property will resolve to the System32 directory on 32-bit machines and the SysWow64 directory on 64-bit machines. Using this property ensures msiexec.exe can always be located regardless of the operating system version on the target machine. The Arguments attribute is used to let msiexec.exe know which product to uninstall by passing in the ProductCode for the install package.

To avoid ICE validation errors at build it is important to couple the Shortcut element with a registry entry and a RemoteFolder element. Both of these are described in more detail in the How To: Create a Shortcut on the Start Menu topic, and are shown in the complete sample below.

The Complete Sample

The following is a complete sample that uses the above concepts. This example can be inserted into a WiX project and compiled, or compiled and linked from the command line, to generate an installer.
