Deactivate the apps with erasure of the number, make a list, activate again by inputting the serials, tick them off on your list.

Matho4 do you have the serial numbers available somewhere?  If so you can go into Photoshop and select Help>System Info and it will have a field titled Serial give you the first 20 digits of the serial number.  The complete 24 digit serial number is not avalable for users to view on their computer.
