The only sorry solution it gives you is to try the upgrade again, which doesn’t work. Clicking on the Go online to resolve this issue link doesn’t seem to take you anywhere helpful either. After doing some research, I figured out what the problem was and was finally able to get the client’s PC upgraded. Basically, it stemmed from the fact that Windows Update had downloaded Service Pack 1 onto the computer, but it was not installed by the client. Because of that, Windows Anytime Upgrade thinks that this is some sort of partial installation and blocks the upgrade. In this article, I’ll walk you through the possible solutions. If you are still having trouble or get this error, post a comment here and I’ll try to help.

Method 3 – Uninstall SP1 Beta

If you installed the beta version of Windows 7 SP 1, then you have to uninstall that. Again, it’s two different commands, one for 32-bit and one for 64-bit. You just have to open an elevated command prompt like I showed in Method 2. Then run the following command for 32-bit: And run this one for 64-bit: If you’re still having issues with Windows Anytime Upgrade failing or giving error message, post a comment here and I’ll try to help.
