I have 2 Parallels licenses on my account. Ver 12, & ver 13. The ver 12 computer died a few years ago, but I still have the license. I have a new to me macbook air from mid 2012 currently running OS 10.13.6. I ran the Parallels 17.0.1 trial with no problems just a few months ago on this macbook. When I recently tried to purchase from the ver 17 trial prompt, I could only DL ver 18... It won't run on this machine. Can I purchase a key for ver 17.0.1 (51482)? Or better yet, can I transfer my second license from the dead computer to the new macbook? I have no problem loading the Mac OS that best matches my ver 12 license. Thanks for the help.
