I wanted to let everyone know that if you can still boot into VirtualPC on your old machine, or if you have proof of purchase, you can call Microsoft at 800-360-7561 and ask them to send you a replacement CD. They will ask for either the proof of purchase, or a multi-digit number that can be found in system properties. Once they have this information to show that you have a valid copy, they will send you an install CD at no charge. I know there used to be a $25.00 fee or something like that, but this is no longer the case.
