I have installed CS 5.5 Web Premium on my new Windows 10 machine and it works fine in "trial" mode. It accepts the serial number but says that is was an upgrade (correct) and asks for the serial number of the program I upgraded from. However, it only offers me Adobe Design Standard CS5 / 5.5 or Adobe Production Studio, neither of which I own. I upgraded from Adobe Creative Suite 3 Web Premium , which I still have and which appears in my product history on the Adobe site. What do I do now?
You could try installing CS3 but you can never activate it because the CS3 activation servers were decommissioned years ago. If your upgrade disk won't accept CS3 as a qualifying product, I don't know what more you can do. Creative Suite is no longer sold or supported so Customer Care agents can't help you.
