Hello: I just migrated Windows XP with all files from my VAIO laptop to a new iMac but cannot even use Windows! The problem I have is when I start Parallels Desktop and Windows starts a message appears "You will need to activate your copy of Windows". When I click OK a blue screen appears that says "This version of Windows is already activated - Click OK". When I click OK Windows logs off and I return to the start page with my user account on it. I click on my user account and the same repeats again! I cannot get anywhere with this Parallels software. Has anyone run into the same issue before? Have you managed to find a solution? Unless this can be solved I can only conclude that Parallels is one of the most useless pieces of software and really need a refund - WITHOUT spending extra money for phone tech support. Any thoughts please?
