You'll need to look at the code to see what it's doing that is unsupported. Many installs don't bother with self-registration. That data is all static data that can be extracted once and included in the MSI file in registry entries and other COM class tables.

This means that there is no need to run code at all during the install. In other words: what is the crucial change after Windows XP? I meanwhile also checked that the MSI works when I run it as an administrator As I figured out reading the WiX toolset documentation, there is an attribute Impersonate for CustomAction that controls if the CA is executed with elevated privileges:.

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. The value I observed in my MSI is decompiled into this:. Translated into my MakeMsi script, I had to use the System attribute in the Type of the ExeCa command as to make self registration work as before :.

I'm fully aware that this is only a workaround, since running a COM server for un- register is dangerous.
