I have an old Parallels 10 desktop for Mac that I would like to install on a OSX 10.7.5 Mac that I have. I have changed the PC with the same HD and now the Parallels need to be reinstalled. When I attempt to install it and enter my license number I get a popup window saying "Unable to confirm the product license. You have reached the maximum number of activations available for your activation key." I have seen a similar post and I have executed the command <><> prlsrvctl activate-license-online <><> inside the Terminal window, but I have ahain the message. I ask you to reset my Parallels Desktop key for me if is possible! Thank you.
