I have been trying for weeks to ugrade the Boot Camp on my XP partition! I have a 17" MacBook Pro and ugraded to Snow Leopard and now have Boot Camp 3.0.1 on my MAC partition BUT have continually failed to ugrade the 2.0 on the XP Partition. (And because of that, I can't donload the Windoes Service Pack 3). I keep getting a message that the ugrade can't access an approved BootCamp.msi even though I have the Snow Leopard disc in the drive plus a copy of the files under C: Boot Camp. I even tried downloading the ugrades on a separate DVD AND I did all the InstEd steps, checked that there wasn't more then one display device in the System folder, check for the Language cose, and dropped the Launch Connection - all to no avail.
Why is this such an impossible task?

Just a simple upgrade to Boot Camp 2.1
