product key help

I have the game installed on my laptop. However I want to install it on my desktop pc. The problem is I can't find my cd case that has the key on it. So is there anywhere I can look on my laptop and find the product key for the game? Thanks

errr .. there isn't any product key for Live 2000

If there isn't, sorry. I thought sure that you had to put in something numbers and letters to prove that you bought the game.
