Just purchased parallels desktop 12 but when activating it asks for an old licence as upgrading but the old version was uninstalled a long time ago and the only key I can find it is not accepting. Any advice?
Hello @DavidW17
Are you trying to enter Parallels Desktop 9 key to activate Parallels Desktop pro edition? If that's not the case, let us know the upgrade license key version which you've entered during the activation process.
Hi
I just accepted offer to upgrade from Parallels Desktop 9 to pro edition.
However, when entering the key from previous version activation does not go through. What can i do?
