    Hi, I purchased the Parallels Desktop 9 for Mac back in 2013 and have been using it ever since. When I upgraded my operating system to macOS Monterey version 12.1 yesterday, I reinstalled the Parallels Desktop software which happen to be the latest version. However, after I put in my product key for the old version, I got an error message saying that "This key cannot be used to activate Parallels Desktop". Could you advise what I need to do to start using the software again? How to switch back to my old version if needed?

    Thank you.

    Hello, With Mac Os Monterey Parallels Desktop 9 is not compatible. You need to upgrade to Parallels Desktop 17 for using it further. Please purchase Parallels Desktop 17 upgrade from this link.
