So, I received an installation disc for Windows 7 Professional, 64-bit, for Christmas today. I am currently running Vista Home Premium, 32-bit. When I go to upgrade to Win. 7 I receive the following message: "This installation disc isn't compatible with your version of Windows. To upgrade, you need the correct installation disc. For more information, check your computer's system information. To install a new copy of Windows, restart (boot) your computer using the installation disc, and then select Custom (advanced)." From my rudimentary searching I have noticed others getting this as well, but it always seems to be with people going from Windows XP rather than Vista. Is there any way to go about upgrading rather than a clean install? Any information would be very much appreciated and thanks in advance!
