Cannot start app in Qt Creator

[giantdragon]

Just auto-updated to Qt Creator 2.2, but when I try to launch my app in release mode I got an error:

Starting C:\...\MyApp-build-desktop\release\MyApp.exe...
C:\...\MyApp-build-desktop\release\MyApp.exe exited with code -1073741511

Starting C:\...\MyApp-build-desktop\release\MyApp.exe...
C:\...\MyApp-build-desktop\release\MyApp.exe exited with code -1073741511

To copy to clipboard, switch view to plain text mode 

In debug mode all works fine. Also app normally starts when manually launch exe-file outside QtCreator.

The error code indicates some dll problem, so check for duplicates (different versions of the Qt run-time dll) in the path, also check the windows\system32 (maybe some other application installed some Qt dlls there).
