Hi Juergen, Removing the listed files did the trick. Thanks a million.
I'm not sure where they came from. I noted that Vectorworks 2019 installs files of the same name in its application folder. This makes me wonder if the ones in the system32 folder might have been installed by a previous version of Vectorworks. This is a complete stab in the dark though.

Nope, you have Qt5 in system32 - that masks the Qt5 that comes with QGIS. If you removed c:\windows\system32\QT5GUI.DLL c:\windows\system32\QT5NETWORK.DLL c:\windows\system32\QT5WIDGETS.DLL c:\windows\system32\QT5OPENGL.DLL c:\windows\system32\QT5XML.DLL QGIS will probably start. Any idea where that came from? Jürgen -- Jürgen E. Fischer norBIT GmbH Tel. +49-4931-918175-31 Dipl.-Inf.
