    I have been using parallels desktop 18 (lifetime purchase) with my m2 macbook air for 1.5 years.Now, I bought a new macbook air with M4 and then I transfer my folders from old mac to the new one. when I try to install and open, it asks activation key. My parallels desktop 18 lifetime activation key doesn't work. It ask me to upgrade the parallels to Pro version. How can I continue to use my lifetime parallels with my new mac

    after downloading legacy version. I got this error;
    '' The configuration file you specified is invalid.
    Make sure that the specified file is a valid Parallels virtual machine configuration file and it is not corrupt, or select another file. ''

    If I have to pay and upgrade my parallels desktop, I certainly want a refund. what is the meaning of lifetime purchase then. It has only been 1.5 years. it is preposterous

    Customer support just sent me this:

    Hello, Please note that Parallels Desktop 18 is not compatible with macOS 26: https://kb.parallels.com/en/114381 We suggest that you purchase an upgrade key at a discounted price: https://www.parallels.com/desktop-upgrade/ We remain at your disposal for any further queries.

    The thing is, I transferred the license back to my M1 MacBook Air, which is running MacOS 26.5.2, and it works just fine.
    SO, it is definitely not a MacOS 26 issue
