Hi,
Never saw this with any previous version, but after installing Fusion Studio 17.2, at startup got a qt platform window error.

After investigation, it is because I have python36 installed on the same machine. Renaming C:\Python36 make fusion starting.
Now:
- Create a C:\Python36 empty folder -> error
- Copy Qt5Plugins folder from fusion studio in this empty folder -> ok
Seems Fusion Studio 17.2 mix its own path

C:\Python36 isn't in my path environment variable, no qt path either ...
