This is actually a really intresting read and the timing of being able to validated the serial number before and adobe turning inforcing TLS1.2 on Jdoes fit as I am only now experiencing this problem. I spent time on adobe chat last night and they even issued me a new serial number, but that didnt work either and now they wont talk to me in chat saying the product is no longer supported. The strange thing is that I reformatted a machine last month and its all OK.
I also tried from home and through my phone just incase our work router, internet, virus protection software was casuing issues. I have tried this on both a Sierra and Yosemite Mac, both freshly reformatted and I get the same problem. If I hit retry it will come up with the same screen again and if I hit connect it will let me install and even run updates of the programs but won’t validate, which will only leave the software useable for 7days. When I try to validate the serial number it comes up with a “Please connect to the Internet and retry” error, saying it isn’t connected to the internet. I cant get it to validate a legit serial number that is registered to my adobe account. Has anyone else had trouble validating serial numbers during the install process of CS6 in the last week or so?
