I'm fine running Windows 7 by booting up with bootcamp on my Mac. When I run the same Windows 7 from Parallels I keep getting a dialog box indicating I have an Illegal copy of Windows 7-- the System runs but I keep getting the annoying message about registering again with the proper key. When I input the key number from the same Windows 7, MS says it's not a valid number. Also I get a message in the lower right corner of the parallels Windows7 window saying this copy of Windows 7 is not genuine. Does Microsoft think I'm trying to run Windows 7 on two seperate machines? How do I get Microsoft to recognize a legal copy of Windows 7 when it's running under Parallels 6? I have only one Windows 7 installed in a Windows 7 Bootcamp partition, which both Apple Bootcamp and Parallels use. Thanks to anyone who can understand and fix this.
