Hi i've just gone through the install of Parallels 8 (trial version). i already had windows 7 on bootcamp and OSX 10.8.2 on my macbook pro. When launching the windows version of excel for the first time i get this message; "Microsoft Office has detected a change in your hardware. Please activate" i tried to go through the activation process but was told that my copy of excel had already been activated. This i knew and i also knew that my office was a single use. Do i need to buy a new activation of excel to use it via parallels? I'm accessing it via my OSX and i installed Parallels via the bootcamp route so i'm guessing that i'm entering excel via my already installed version on bootcamp. thanks Shane
