I have an installer that works perfectly under NT 5.x, Vista, and Windows 7. It contains the proper manifest for UAC on NT 6.x.

But starting with Windows 7 RC, every time the setup program closes, Windows produces an erroneous "This program might not have installed correctly" message, even though the program did install correctly with no problems whatsoever. I never got these spurious messages in Vista or in Windows 7 beta.

I sent a bug report to Microsoft, but have not heard back. I thought that this might just be a glitch in the Windows 7 RC, but the problem is still there on a fresh install of one of the very recent RTM-escrow builds that was leaked. Microsoft has no documentation whatsoever about this--not even a hint to what might possibly be triggering it.

Even more frustrating is that I get this "This program might not have installed correctly" message even if I cancel the install on the very first are-you-sure-you-want-to-proceed screen before any of the installation code (creating a temp dir, extracting files, copying, registry, etc.) is ever run.

Has anyone figured this one out?
