Maybe a dumb question, but I am not able to find a solution within forums:

I've developed an app with Visual Studio 2005 SP1 using QT4.4 under WinXP SP2 32 Bit. Building and launching within VS2005 works without any problems, but starting the previously built application by clicking its icon in the Win Explorer gives the error

Microsoft Visual C++ Runtime Library: Runtime Error!

without any further information.

Does that sound common to anyone? Thanks for reading.
