I'm trying to upgrade a computer from Vista Ultimate (32 bit) to 7 Ultimate (32 bit) and I keep receiving this error 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)."
Now, I double-checked all the system requirements and the system is compatible with 7.
