Hello IsaacF, We have made the necessary changes for the Parallels Desktop license key. kindly try to activate it. If the issue still persists, please execute the following command with Terminal < prlsrvctl activate-license-online >. May I know the Mac OS X of the computer in which you are trying to activate the Parallels Desktop 10?Hi I'm trying to Activate parallels 10 on my Mac and keep getting a connection error: "Failed to activate the license: Unable to confirm the product license. The operation failed due to a connection problem. Please try again later or contact the Parallels support team for assistance." My support code is 77866-19537. I tried rebooting and all of the other suggestions in here including running the prlsrvctl command from terminal. I think my license key needs to be reset like everyone else, could someone please do this for me?
