Yes, you can definitely move it, or if you have the boxed version(w/discs), you can use those, you can only use it on one computer at a time. There are plenty of posts on moving to different PC, I personally have not had to, so I can't help you, but thats why I get the box version of everything I purchase, just for that reason, or more importantly, if you have a total crash, just easier, than downloads, not a big fan of them!
