Proxy was turned off in Win 10's settings, but Firefox had some sort of proxy set: data:text/javascript,function FindProxyForURL(url, host) {if ((url.indexOf("proxmate=us") != -1)) { return 'PROXY us08.sq.proxmate.me:8000; PROXY us05.sq.proxmate.me:8000; PROXY us07.sq.proxmate.me:8000; PROXY us02.sq.proxmate.me:8000; PROXY us01.sq.proxmate.me:8000; PROXY us09.sq.proxmate.me:8000; PROXY us06.sq.proxmate.me:8000; PROXY us11.sq.proxmate.me:8000; PROXY us13.sq.proxmate.me:8000; PROXY us03.sq.proxmate.me:8000; PROXY us12.sq.proxmate.me:8000; PROXY us14.sq.proxmate.me:8000; PROXY us10.sq.proxmate.me:8000' } else { return 'DIRECT'; }} I switched to no proxy, and tried running the installer again. This time it got as far as to ask me to close Firefox, and I thought now it's working - not. Foiled again. In the end I downloaded the offline installer, and it installed without any problems whatsoever. Maybe you should make it easier to choose the offline installer, like offer a link on the page I linked in my first message. I hope you manage to find the bug, so that others don't get the same problem in the future.
