Hi koahning, I've had a similar problem. Maybe my bugreport helps: https://bugreports.qt.io/browse/QTIFW-1003 After installing notepad++ and assigning ".vbs" extension to it, windows wasn't able to execute ".vbs" scripts anymore. Resetting the assignment in the regedit (HKEY_CLASSES_ROOT.vbs to "VBSFile") solves this issue. Maybe this solves your issue, too. Regards Jazzco
