Application works when started from VS2005, breaks when started from explorer

%SystemRoot%\system32 is set within PATH. I think it would break with a message like "*.dll could not be found" if it weren't so

Are you launching the program on the same machine?

If no: check if you are trying to launch a debug version. Since Visual Studio 2005 it is impossible to ship a debug version to a computer that does not run Visual Studio.

If yes: Check if the required Qt (and other) libraries are placed in the application directory (recommended) / system directory (if you are not afraid of dll hell) / PATH (if you are not afraid of dll hell).

To figure out which libraries your program cannot find I suggest using Dependency Walker.

Yes I am.

Dependency Walker tells me, that every library can be found (except the well known msjava.dll issue)
