This is serious. I downloaded the latest SketchUp 2020.1 Update and received the messages below.
So, after many tries, I uninstalled the ‘original’ 2020 version and ran the installer again (in Admin) with the same result.
Problem is, now I don’t have 2020 installed, don’t have a way of installing it and have 2020 version files which can’t be opened.
I’ve tried to clean up any remnant 2020 information as best I can. I do note that others have had similar or exact same messages but not seen how they actually fixed their problem.
Trimble haven’t been back to me with any kind of answer.
