Jo Mamma is right -- including software on a machine with license constitutes piracy. You yourself say that it "must be used in accordance with software copyright laws" which means deleting it right after they receive it since they don't own the license.
The seller should really delete the software, but if they're too lazy or what not they should tell the high bidder to do so after the auction is over, and certianly not mention it as a selling point in the item's description.
