Two Plus Two Newer Archives - Getting current PT onto a new computer

Just bought a new laptop, going wireless. Used to play all my online poker on our current desktop. The desktop isn't going away, and while I likely won't play much poker there, I might still play on it. Ideally I'd like to have my working PT db plus current hand history on the desktop still (and if possible, I'll have the two networked so I can move the actual hh dbs back and forth).

The question is, how do I get PT onto my new laptop? I went to download it and it said not to download it again cause it'll change the registration key. Can I dl it anyway, get the changed key and use that on the new laptop version, then enter that key also in the desktop version? Simply move the PT program over from my desktop to my laptop? Other suggestions?
