Hi, I just updated my MBP to El Capitan with a clean install and moved all my data with migration wizzard - when trying to run Parallels Desktop 11 it tells me, that it is already activated on my desktop Mac. This is correct. Somehow I never noticed that EULA allows INSTALLATION on only one computer but thought that the USE is restricted to one machine only (I mean: you can install and activate it on several machines, but are not allowed to use the installations simulaneously) ... Never mind. Since I need to be able to run Parallels on both of my MBPs and my desktop Macintosh, what are my options: buy two additional full licenses? I'm a user of Parallels since version 5 and made all updates. Can I buy 2 more updates from 10 to 11?
