You also need to deploy the MINGW runtime dll (mingwm10.dll). This file is located in your Qt\2009.5\mingw\bin directory.

Also pay attention to whether your application is compiled in debug mode or release mode. I just made the test with an hello world type application and Qt Creator. In the debug folders, I copied libgcc_s_dw2-1.dll, mingwm10.dll, QtCored4.dll and QtGuid4.dll and it works.

Pay attention to the d in dll names, which stands for debug: QtCore d 4.dll.
