I just transferred my classic license for SketchUp Pro 2020 to a new iMac. Since my license was almost up for renewal I renewed it for another year. As I recall (this was a week ago), I re-activated my new installation and license.
I can open a SketchUp file either by double-clicking on the file or from the “open recent” list in the application. I just get the normal warning message about the model being last saved in an older version. I can use Save As to the same filename, which I normally do, with no problems.
This morning I opened a LayOut file by double-clicking on the filename. When I first tried it I got a message saying the SketchUp license was not valid. However, when I double-clicked on the LayOut application in my Applications folder, everything was honky dory and now I can open the LayOut file either via the open app or by simply double-clicking on the filename. I also get the warning about the older version. However, when I try to Save As to the same filename, I get this message
If it’s complaining about the apostrophe, that boat don’t float because Mike’s Stuff is the same directory where I just did a Save As on the SketchUp file.
Okay, so what am I missing?
