After cloning my HD for the purpose, I attempted to upgrade my WinXP SP2 to
Vista Ultimate RC1. The process proceeds normally, entering the product key,
etc, and completes the "Copying Windows files" phase successfully. However,
about 35% of the way through the "Gathering files" phase, it throws up the
message, "Windows installation encountered an error and cannot continue,"
whereupon the process terminates and I'm back to my WinXP desktop. I have
gone through this twice, with the error occurring in the same place both
times.

My system meets all of the criteria for Vista Capable and I had disabled my
antivirus (AVG).

What could be the problem here?

I can also now report that I reburned my Vista Ultimate RC1 DVD at 1X,
then tried the upgrade again, and it still failed, with the same error
message, during the "Gathering files" phase at 32%. So it doesn't seem
to be an issue with the DVD.
 
I had a similar problem (no error message) Install just hung, three quarters
of the way. I tried twice, then decided to do a clean install instead of the
upgrade from XP sp2 and it loaded fine.

But I am interested in doing an upgrade, not a clean install, and would
like to know why I can't. When you attempted an upgrade, did the problem
occur during the "Gathering files" phase?
