The first screen now shows that I have a license available. If I select this one, I will be asked for two license keys. One is the Parallels 11 one and the second one will be one of a full previous version. Still the second one does not get accepted. Do I need to deinstall Parallels 11 and reinstall it? Or what do you suggest? Thanks, KohnHi, please provide us with the screenshot of this message. Thanks in advance.
