I need to upgrade Windows 7 Home Premium to Windows 7 Ultimate. When I run the Windows 7 Ultimate setup.exe that I downloaded from my MSDN subscription, it says
"Windows 7 Home Premium cannot be upgraded to Windows 7 Ultimate N. You can choose to install a new copy of Windows 7 Ultimate N instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows 7 Ultimate N, click the Back button in the upper left-hand corner, and select “Custom (advanced)”.
Anyone know what to do? I'm hoping I don't have to purchase the upgrade through Windows Anytime Upgrade, because I've already purchased this software through the MSDN subscription.
