Gave me the same error Unable to get setup from ... I used the new setup-x86_64.exe from Cygwin.org and had to select the Use Internet Explorer Proxy Settings option.
He selected mirrored URLs. It worked for me.
But, if he does not select all the mirrors on his own, we can add the url http://mirrors.kernel.org to the download list.
Initially, when he did not download the list of mirrors on his own, I tried to add the http://mirrors.kernel.org url above manually, and it worked like that too.
