Hello,

After install OpenVPN Client GUI, I'm catch error:

disabling NCP mode (--ncp-disable) because not in P2MP client or server mode
Options error: You must define TUN/TAP device (--dev)
Use --help for more information.

TAP driver installed, reinstall OpenVPN Client (with driver). another PC connect not error.

From experience, what could be the matter?
