Windows 10 lasted for about a day in our house. One of the programs we use every day doesn’t work on windows 10 unless you get the new “app” version, which is subscription based instead of straight purchase or free.
Nope not gonna happen
OK, I’ve got to know the name of this supposed program that somehow doesn’t work just because you installed windows10.
I use an old copy of Paint Shop Pro from 1999, that I run from a thumb drive and a strategy game I’ve been carting between computers since Windows 98 and both work completely fine.
If this is some win32 program it seriously isn’t actually telling you it isn’t working.
