H I am using parallels for mac 10 version. My computer broke down... And I proceeded to install the new version, but I received a message saying that authentication could not proceed and asked to proceed. What should I do?
Hi Cindy, Did you purchase version 12 though as your license for Desktop for Mac 10 will not work with the latest version. Kevin
@CindyS2 also if you would like to activate Parallels Desktop 12 you need the version 10 key for activation.
