Sorry that I become in thread.
I said that I am testing in native windows
I have installed all working in GD2 v 19.0.05700
All SAAB 2018.1, GM Global 2018.3 and Opel 2018.3.
Then in GDS2 v20.022300 only the GM Global 2018.6 can be installed.
True I don't even downloaded your VMware because I have it installed in native windows.
I already said this.
I don't need vmware at all. I just said what I said but I don't know what solution didi you use.
I belive you change the GDS2 version between them to works with one package version that need this version 20.0.022300 and then go back to v19.0.05700 to works with the other packages.
Don't worry I just said what I said I didn't said that I tried your work and it wasn't good I just said that its not possible to use newer GDS2 version with older pacakges ( as you can see there is"Request upgrde" which is mean that need other version of GDS2 to works )
And you was agree with that.
I didn't say nothing more so stay calm your works its appreciated by the one that use it

Good luck
