Windows Anytime Upgrade Fails

It did have Mcafee installed as well as Nero. I removed those, but mistakenly tried to upgrade with them installed the first time.

I'll run the 'panther' search in a bit when I get back to the PC. Thanks everyone!

these are the only listing I get when I search for panther

Here is my Upgrade log. Not sure what the error transmogify is? But I think the issue is with the license key in the registry. It never prompted me to use the license key that I got when I purchased the software. It bypasses that step. SKU fail makes me think that the program is trying to use the key dell provided OEM? does anyone know what key to remove in the registry?

Do you have access to a Win7 installer to do a Repair Install?

A Win7 installer with SP1 (not slipstreamed) can do the Repair Install while installing SP1.

Here are tips to get a perfect reinstall: Reinstalling Windows 7

Thanks everyone. I reinstalled Home Premium and went straight to the upgrade before doing any updates. That seemed to work. Perhaps not the simplest way...
