I have to set up Parallels Desktop on an older machine running OSX Catalina. I was able to download, install, and operate the software. However, when I try to buy a license key, the shopping cart says that I'm buying version 26. Will this work? I don't want to pay $219 just to see if the license for version 26 will work to activate version 15.
How can I activate version 15?
