“This program might not have installed correctly” message in Windows 7 RC

Question

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, ever

Answer 1

I ran into the same error message when running a new Qt based app I built. Same symptoms - would get this 'helpful' message after the .exe closed, no matter what the program did.

Now I have various qt app projects, all built the exactly the same way. And none of the others do this.

I finally figured out that this error was caused solely by the fact that I had named this particular project 'installer'. I had ended up with a binary 'installer.exe' and it would have no doubt had the project name built into it elsewhere (without delving into the qmake generated project file, not exactly sure what).

The point of interest is that you can run into this problem simply by having a project called 'installer' and nothing else.
