Adobe turned the license servers off that the installers used to verify your CS6 installer key. No check pass, no install. Of course, you can just use an LLM to build a patch, or pirate a copy, but it's the principle I suppose.

CS6 verifies keys locally if it can't reach adobe's servers. Are they specifically blocking that?

Blocking CS6 from accessing the internet in your firewall and using a key somoene posted online was a common practice back in the day.
