Windows 7 - Upgrade Windows 7 Professional to Ultimate

Hi,

I have Windows 7 Professional (64Bit) installed and attempted to upgrade to Windows 7 Ultimate (64Bit). My DVD has 32Bit and 64Bit. Clicking on 64Bit and going forward, I receivee a message saying that I can't upgrade to 32Bit from 64Bit and the installation (upgrade) stops. As stated, I clicked on 64Bit as previous edition.

What could be the issue?

Many thanks in advance.

Regards,

Do a clean install, not an upgrade

Hi,

Thanks for your reply. Much appreciated.

Was just trying to avoid a clean install.

Thanks again.

A clean install is not a big problem. You can use windows easy transfer for settings, cookies, desktop etc. Then reinstall programs as you need them.

The issue is that Windows 7 wants you to use Anytime Upgrade to upgrade within Windows 7.

There is a workaround which can be adapted to do an inplace Upgrade here: Upgrade the Windows 7 RC to any retail version Icrontic Tech

By changing the shown Registry keys to Ultimate exactly as shown, it tricks the installer into thinking you are doing a Repair Install (same version Upgrade over itself) which is allowed.
