I currently have Adobe CC on my main machine, but I wanted to use an older machine with an older version of CS. I did have a License for CS5.5 and have a physical copy of the software, how ever now I am installing it, it is asking for a key code that was emailed to me.
My old machine needed a serious reinstall and all data was removed. Hence me now trying to reinstall.
I no longer have that email, can I retrive this old infomation from Adobe so I can run an older copy of CS5.5?
If you originally purchased your software directly from Adobe and/or registered it with the company at some point, or if you're certain that they had emailed your license key to you, then they may have a record of it online.
Check your online Adobe account to see:
Hope that helps!
