Windows uninstaller not working as Admin

I made my own installer / uninstaller. I register the uninstaller using the Windows Registry as described in MSDN Library, Chaper 2. Install / Uninstall.

Namely, it means registering uninstall.exe

as UninstallString

. It works as it launches my uninstaller. The problem is that it is not called as admin. I have set up a manifest uninstall.exe

requiring admin using mt

and if you double click it from explorer it will automatically prompt for admin at will.

So the question is, what magic flag do I need to set in the registry in order to open the Windows Add / Remove Programs dialog box to run my uninstaller as administrator?
