Hi all, I have had Parallels 5 installed on my 21" Imac since April this year when i installed a genuine brand new retail copy of Windows 7 Ultimate with no problems.I have not used Windows for a couple of months now but have tonight started up Windows and it is now telling me i have an invalid product key?. This copy of Windows has never been installed on any other computers and has also never been used for Bootcamp on this Mac,so at the moment i am very confused,any ideas? Regards Nigel.
