Can anyone help with this problem? My Guest OS is Windows 7 which I had installed on my Boot Camp Partition before installing Parallels Desktop 6. When I boot up my Boot Camp drive independently all be Microsoft software is activated. When I boot up my guest OS via Parallels Desktop 6 my Microsoft software requires Re-activated, which I believe to be due to the Virtual Machine. However my Microsoft software states that the software cannot be activated because the specified Product Key has already been activated. Is there a way that Parallels Desktop 6 can rectify this problem? My Microsoft Software is: Microsoft Office Professional 2010. Microsoft Visio Premium 2010. Microsoft Project Professional 2010.
