Hello
For me it looks like permissions related, try to run the agent using "Run as administrator" and run it as process or simply try installing a LG on a NON server windows, such as windows 7 o windows 8, this in order to verify or deny the permissions are related, same for controller, if it is running on a server windows version, then use "run as administrator" and avoid using the controller as LG as well.
let us know the outcome
regards
