Just so we`re on the same page: It appears that the problem I was having to install SDL2019 was that the new Windows 11 system (Japanese language version) has a feature called smart app control - that blocks installation of any software Microsoft does not recognize. Once I understood that irritating feature I was able to turn it off while I completed the installation. It appears that SDL2019 is installed.

However, I am unable to deactivate my previous version on my old machine. I need help returning the license so I can activate my newly downloaded version on my new system.

I`m hoping someone can help me with that.

Thanks for your attention to this silly and probably easily solved problem.
