How do I set the proxy, so I can register wolframscript behind a fire wall?
Mine failed to auto detect the Windows proxy settings so initially I couldn't activate it "(7) Unable to connect". Then @Arnoud Buzing suggested me to try setting up http_proxy and https_proxy environment variables and it worked that way.
This is not ideal at all in corporate environments using PAC files for proxy configuration.
Thanks! I'll look into that.
