lost my product key for PSE 11

If you do find a serial number on that computer it will be 6 groups of 4 numbers
Such as 1234-5678-1234-5678-1234-5678

This time, write your serial number on a piece of paper and put it in a desk drawer

you have 3 ways to recover a serial number that you once had:

1. if you purchased from or registered with adobe (automatically done with cs6):,

    a. you can check your account, https://accounts.adobe.com

    b. you can check with adobe support* (be prepared to give the email address used when registering and/or          purchasing)

2. if your adobe program is installed on another computer you can recover its serial number from that computer,
