Quoted from Omega_2:

All I know is that avast didn't even need to be OFF in the first place, for Windows Firewall, you'll have to set it to ignore/allow that app In Windows 7, you can put this in any Explorer window with an address bar, and either check for the app in the list, or add it:

Control Panel\System and Security\Windows Firewall\Allowed Programs

Allow it on BOTH Private AND Public networks, just to be sure. And I'm pretty sure it's Python that needs to be allowed, too.
