Adobe Acrobate 8 and 9 pro product keys

Im trying to locate the keys to put in my inventory here at work, so we will know what is in use and what isnt out of our list. How can I figure out the product key for acrobate 8 pro and 9 pro?

Ive tried going to help and about adobe acrobat pro on acrobat 8 pro... tells me the first 5 grpd numbers but not the last grp. Where do I get the whole key?

For Acrobat 9 I cant find any of the key at all. Where do i get the key?

Ive tried keyfinders and all the ones ive tried that are free dont pull the Adobe keys.

Any help would be appreciated.

Thanks.
