I have the latest version of SU Pro v2021. I open the desktop shortcut and create a new file and save to a project folder. When I attempt to open the .skp file in the project folder, I get a message that it was created in a newer version of SU.
If I do a right click on the same file there is no option to open with V2021. I have tried reinstalling and using Admin permission still no luck
I had a similar problem with v2020 and the right click option. Someone had a fix that required downing a patch or .rbz file and that fixed v2020 .
I would love to resolve this so I can open the file from the project folder instead of having to using the desktop shortcut each time first then having to do open file and so on.
