Query: Don't buy this if you have windows XP!

It doesn't work on XP, even though it clearly states that it does on the box. What a joke!! It won't install because it thinks there's another version there, but there isn't so there's nothing to uninstall. Who makes software that can't uninstall itself? Who makes software that can't upgrade itself? Roxio took a decent program and trashed it. If you don't believe me, go to support.roxio.com. Enter the message board for this product and do a search under "installation". You will see thousands of hits with the same problem.
