Answer 1

The solution for me was enabling TLS 1.2 support in Internet Properties. But hold on! You'd better update your Windows before, because there is an update that enables support for this protocol by default. If you don't want to update your Windows, for reasons, follow these steps:

1. Go to Internet Properties, you can find this in start menu, in control panel, or hit Win + R and run: Inetcpl.cpl.
2. Go to "Advanced" tab.
3. Scroll to "Security" section.
4. Check Use TLS 1.2 option.

Run Cygwin installer again and now it should work. If not, maybe try with other security options.

How did I find out this

After a few failed install attempts, I decided to look for some hints in Event Viewer, and to my surprise, I found them. In System logs I spot lots of errors from Schannel service with a meaningless description:

The following fatal alert was received: 70.

I Googled for further explanations. Errors like these are caused by SSL failures, so something wrong was happening between Cygwin installer and Cygwin site. Something in my head told me to check Internet Properties for options relating to security, so I did and I found disabled protocols.
