PCSDK static controller will not connect without RobotStudio running

When testing a PCSDK application, I can only connect to a real controller if the controller shows up in the RobotStudio 'Recent Controllers' list. How do I runt a PCSDK application independant of RobotStudio? I have installed PCSDK 6.07 as well as Robot Communication Runtime 6.07. Yes, I have verified that the specified GUID of the robot is correct. 

Here is the line of code that throws an exception:

Controller @static = new Controller(ControllerFactory.FormatControllerId(new Guid(sysID)));
