Old School is correct that you can not just move it from one computer to the other via thumb drive or burning on to a disc. When it was installed it wrote different registry items that allow it to work on the computer it was installed on. Just copy/pasting on to a new computer would not allow it to work.
If you have the original installation discs you can install it on the new computer because you do own the software. If you don't have the disks but you feel like you purchased the software in a legit manner, then it Wouldn't hurt to check with Microsoft on what you are supposed to do when you get a new computer but weren't given the discs. I'm sure that's a question they have been asked before.
If you find out a solution let me know.
