    OS platform: Windows 7 64-bit
    Qt version: 5.0.1
    Compiler: MinGW 4.7 32-bit
    Build Errors: None

    Additional info
    I have been monitoring the application from task manager. Before this problem, the application's process would run on 34mb of memory. But when I start Qt and build, it appears in the task manager processes and disappears when it reaches around 13mb of memory without showing up on the desktop. When I build for the second or third time it doesn't even show up in the task manager processes

      Does it also happen with a default constructed application ? (new project -> Qt GUI application and just build and run)

        No, it doesn't happen with any other or default project. Just on this project only

            Can you share what the problem was ? That might be useful to others

              I copied all the dlls files needed into the release directory. So the app builds and runs. But it can't run alone without Qt. It terminates with Qt5Core.dll as the Fault Module

                Do you mean starting from QtCreator or directly in the folder containing your executable ?

                  Starting from QtCreator works fine. It terminates with the error when I start the executable directly

                    It actually sounds weird, I thought it would be the executable working fine but its the other way round

                      When you are starting your application outside of QtCreator, the same rules applies as in the "deployment":http://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html documentation
