My PC died very suddenly before I could transfer my Classic licence to my new PC.
I have retrieved my Classic Licence serial number VA-*****- and authorization number from Licence Manager and confirmed with Sketchup support.
When I use the default method of adding my licence, the system response is ‘That doesn’t look like a correct Serial Number and unique Authorization Code for this version of SketchUp’
I have tried manually typing etc.
When I try using the advanced route I get the error message that ‘the licence I added is not a valid Sketchup licence’
Has anyone else had this problem and how did you solve it please?
With help from @Colin of Sketchup team (thank you so much), I managed to work out the issue which I am posting here for the newbies like me :):
Sketchup annual releases are tagged with recognizable letter suffix which changes each year.
For example, a serial number of V*-***-, V means it is a 2020 release, U means 2019, T is for 2018 etc.
If your classic licence is from 2020 (which I think is the last year that you could get a classic licence?), you need to download the 2020 Sketchup version.
