Lost Word 2K CD Key

Hello!!

I have Word 2000 loaded on my Win98 SP2 machine (have original Word install CD). I bought a new machine (WinXP) and want to move all my software to the new machine, but lost the Word 2000 CD Key for the install. Is there any way to find the key on the old computer (such as a registry key, “About Word 2000”, etc.) or any other way to install this program?

Thanks!
Geoff
