I am selling my late 06' MBP. Obviously I am going to wipe the HD so I can pass it on to the next owner as a clean slate. I want to offer them the MS office 2004 (i know old) as an incentive because I am done college and I have a friend with a code for a newer version. If I wipe the HD, then that means MS office goes, and if the customer tries to type in the code to the MS office when putting it back on the MBP, will it not work because it has already been registered and used? Help appreciated, thank you.
