Situation
I want to install minGW and msys on a work pc, but I'm behind a proxy. The proxy settings are configured to auto detect in both internet explorer and firefox. The proxy is a http proxy on port 80 that requires authentification.
I also have the url of the proxy and a .pac configuration script.
The system is windows 7 64 bit.
Problem
MinGW setup does not recognize the proxy settings and therefore cannot download any packages for installation.
What I've tried so far
I've tried changing the proxy settings in the internet explorer's internet options from auto detect to manual setup. I've also tried running the installer through proxifier. Both didn't work.
