After about 20 minutes of installation time, all of a sudden I get a
message that a file cannot be copied/installed (NO mention of file)
and installation quits. Now when I start the computer up I get a
screen that forces me to select either continue update or go to
earlier version of windows (listed as a windows boot manager) - would
like to get ride of this as it defaults to windows setup and then it
cannot continue.

Obviously if I could get Vista installed there wouldnt be a problem,
I removed the files that were suggested with Vista compatibility. Now
I wish I had not tried this, but I bought 2 other copies for other
computers! Dell 9300 with Windows Media Center XP.
