    I upgraded from Parallels Desktop Pro v20 today to v26 and cannot Activate or Reactivate my product key.
    Error:
    Unable to verify the license signature. Please try to activate Parallels Desktop.

    Same problem here. I opened a support ticket and received a new, temporary license key that works. They acknowledge there's a problem and they are working on a fix.

    My issue has been resolved, thank you. Despite no change to my local firewall settings, using a guest network allowed the reactivation through.
