Installing CS6 on old computer without old adobe ID
I want to install CC on my macbook, but would like to keep existing my CS6 operational, by loading it on an imac that will keep an older OS just for that. I bought CS6 on disks a very long time ago. Still have the box and all serial numbers, but I don't remember what adobe ID they were attached to. I copied everything to the iMac with Time Machine, inc the software, but now it is asking me to register it by signing in. The only Adobe ID that I use at the mo is linked to a much more recent email address (which did not even exist when I first installed my CS6 copy), and that account has CC subscription, which I can't use until I upgrade the OS on my laptop, which I don't want to do until CS6 works on the desktop. Tried to find a way of contacting Adobe directly but no joy. Any suggestions?
