Can't load Publisher 2000

[Ben]

I have been trying to move Pub. 2000 (used in Windows 98)
from a Hewlett Packard, to Windows XP on a Dell computer.
However, every time I attempt to load the program, a
screen appears saying I need to type in a 25-character CD
key which is on the yellow sticker on back of the CD jewel
case. I did not keep the CD case, choosing instead a CD
holder for all CD's. Is there any way I can find out what
that key is?

Thanks.
