[PROBLEM] VPN with Xbian?

[Dimension]

Sorry to be such a bother but I am still learning Linux and trying to understand what command does what.

I ran the sudo /usr/bin/killall command and was not prompted for a password but when I ran sudo /usr/sbin/openvpn I was returned a message stating 'sudo: /usr/sbin/openvpn: command not found'. It appears that the installer did not work.

AS for the 'openvpn path' I checked the different settings within the addon in Kodi and did not see any options to set the path. Where can I locate the path settings and where should they point?
