Qt 4.7 and Visual Studio 2010 - cannot launch compiled Qt Applications

[Schreihals]

Hey,

i've got a problem with my Visual Studio 2010 (ultimate, out of msdnaa) and Qt 4.7 setup.

i can compile my Qt apps successful, files getting moc'ed and everything looks fine.

but if i try to start my, just compiled app, i'm getting an error

"... exe could not be launched"
"error in application configuration"
"check your manifestfile for errors"
"reinstalling your application may solve the problem"

can someone help me?

best wishes

Hi,

Did you use the pre-installed version of Qt (the one that you don't need to build yourself) ? It might be because of a dependency to msvcrt90.dll. You could open you .exe with depends.exe to show you the missing dependencies.

Rebuilding Qt on your machine may solve the problem, because then Qt is build with dependencies to the DLL's that are on you machine.

Best regards,
Marc
P.S. you may also google for "dll hell" and "manifest hell" :-)
