I am trying to install Adobe Production Premium CS6 (not cloud) on my new PC. I was previously using it on a different computer, and I deactivated the suit on that computer. I'm now in the process of installing the software on my new computer. I've gotten to the point when I am asked for my serial number. I type in the serial number emailed to me by Adobe and hit enter, then I receive a message saying "The serial number you have entered is invalid. Please try again. If the problem persists, please contact Customer Support." I've attempted to enter the serial number multiple times and I am at a loss.
First, verify that you are entering the number correctly
