1) You need to make sure USB file sharing (not just charging) is on for ADB to work. I'm sure this is a bug!!!!!
2) Disable any Anti-virus/Firewall.
(I had an anti-virus/firewall running called Bullguard. The Firewall was smart enough to figure out what ADB.exe was and allow it. But Minimal ADB launches cmd-exe.exe or something and the Firewall was silently intercepting the 127.0.0.1 endpoint.)
also if he emulator fires up do an adb kill-server and try again.
