I had similar problems and there were 2 things I needed to do and then it worked perfectly.

First I had to turn off Norton 360's Auto-Protect feature and the firewall.

That would get me past the rainbow screen and stop Vista from trying to install a new device driver. But then the device would freeze on the progress bar screen with 0 progress and an error message would pop-up on my PC.

I found out this was a common problem for Vista users and that many had been able to successfully update their Mogul by going back to the HTC update page, clicking on the ROM link, and selecting RUN instead of saving to disk.

I was skeptical but I tried it last night and it worked perfectly.
