Cannot Register CS6 on Site

When & where did you obtain CS6 and the redemption code?

I ask because it hasn't been sold legally since early 2017, when Adobe discontinued Creative Suite.

there are 3 ways to find/recover an adobe serial number.

1. search purchased materials: https://helpx.adobe.com/download-install/kb/find-serial-number.html

2. you can check your account (if you purchased from or registered with adobe AND you remember the adobe id used to purchase/register), https://accounts.adobe.com

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

    (win:) http://www.belarc.com/free_download.html

    (mac:) https://mac-product-key-finder.com/

A redemption code may be used only once to obtain a serial number.

Check your account for the serial number and the correct download file:

https://account.adobe.com/products

Thanks for posting your question, PJBlackmoore. Please see https://adobe.ly/41YPVZj for information on how to locate any serial numbers. If you are trying to enter any letters, then you have a redemption code and not a serial number. If this is the case, the serial number will be registered to the account you used to originally redeem the code. Please see https://adobe.ly/424xGl7 for information on redemption codes and https://adobe.ly/4lhXd3h if you need to reset your password to access the account with the registered software. ^JW
