Did your freind register PM wth Adobe? If so, the serial nos should still be with Adobe.
If, as the opening poster says, there are no serial numbers in the original product boxes, then unfortunately they are not legitimate copies, and Adobe will not provide serial numbers for products that could not possibly have been registered.
If your friend just got these applications where did he get them?
Sounds like pirate software as CS2 is no longer being sold its about 5 years old. the serial numbers are normally located on a sticker on the Back of the CD case. Your friend needs to get his money back. If he used a credit card he should cancell it now before the pirates start using it.
I doubt very much the items are the genuine, new and used item, or it fthey were they have been sold on improperly.
