I’m trying to reinstall Sketchup on a new machine. I’ve installed OK, and just verified my license and authorization number online, but when I enter it into the Authorization dialog it returns ‘Serial Number invalid’.
I realize this is an old version (4.0) and that Maintenance support is no longer covered; however it was a condition of the original purchase that this version would continue to work.
Can you suggest any other tips? I’ve tried hand-entering the serial number to avoid dash problems; I’ve looked for a Sketchup.lic file and found none.
