Software Support personnel to resolve your problems. If this is NOT the issue you are dealing with, please contact our Customer Relations at . Thank You, In this post Deon also mentions that for certain Creative Cloud Software License holders that their serial numbers are only available for online purchases. For a while I was having trouble understanding what was happening and how to solve it. After I posted on this same topic I get multiple emails from Adobe saying the same thing. What is “Adobe CS Licensing” Adobe CS Licensing (CS Licensing) is the serial number associated with your product activation of that Creative Cloud Licensing software license. If you have not installed the Software License purchased online before you should take note of the serial number of the license you are activating and then follow these steps to re-activate it. Using Adobe CS6 product activation, you must complete the Online activation process through the following steps: 1. Navigate to the Adobe CS6 Product Activation page and log-in with a valid Adobe ID. 2. Click Activate Product and follow the initial activation steps to complete the product activation. 3. After the product has been activated, you may have the opportunity to access the product in Creative Cloud by completing the initial product activation. What to do after finding my serial number This article suggests to look for our serial number to find out which software license you need to reinstall or upgrade your software, or to re-activate your software license after a product-activation error. My recommendation is to check your serial number at Adobe Support Site. This site is accessible online, so it does not require a log-in with Adobe ID. You need to have Adobe CS6 installed on your computer before you can find your serial number. You can install it by visiting: Here is my advice: Find your Adobe CS6 product activation serial number at Adobe Support Site using “Find Product Activation” or “Find Product Activation Serial Number” or just Google “Find product activation” and “find product activation serial number” (see YouTube video or link below). You need to get serial number of your purchase, not activation date. Do not check your serial number more than once, only on the Adobe Support Site (see YouTube video). Do not email your serial numbers to you.
