Windows Installer would not expand that environment variable, because the Property.Value column has type Text rather than Formatted. http://msdn2.microsoft.com/library/aa370908.aspx Instead, you can use custom action type 51 to assign the value to the property. http://msdn2.microsoft.com/library/aa368237.aspx In WiX, it would go like this, IIRC: <CustomAction Id="SetMyProperty" Property="MyProperty" Value="[%myenvironmentvariable]"/> <InstallUISequence> <Custom Action="SetMyProperty" Before="AppSearch"/> </InstallUISequence> <InstallExecuteSequence> <Custom Action="SetMyProperty" Before="AppSearch"/> </InstallExecuteSequence> Repeat for the other sequences if appropriate. Also heed the advice to add a prefix to the names of your custom properties and actions. http://msdn2.microsoft.com/library/aa370529.aspx
