Well, I’ve never had this happen. I’ve installed Scrivener, a Windows writing software, which I’ve done many times before. To activate the software, I entered my purchased software key, and the registration failed with a “Please enable TLS 1.2 on this machine”.
I have checked and gnutls is installed. I reinstalled just to say I did it. I checked certificates with “trust list” and I have certificates, several certificates. But how do I “turn on” TLS 1.2? I can’t seem to find any answer anywhere except for some wall-o-text server articles that turn my brain to mush, and it’s way too early for that, even with coffee.
