_there_ is your problem. _never_ package the Qt libs from \bin. They are 
private to Qt Creator (They come from a Qt built with Visual Studio), 
wheras the ones in qt\bin are build with MinGW (don't be confused by the 
mingwm10.dll runtime in \bin, it's there for convinience only).

Because you try to run a MinGW-built Application against a MSVC-built Qt.
