Have you looked at: http://forums.station.sony.com/ps2/index.php?threads/the-launcher-is-unable-to-well-launch-planetside2-exe-acess-denied.66550/

From the sound of things it sounds like something on your end is blocking your acess. Try  and set any firewalls and antivirus programs to allow PlanetSide 2 (specifically launchpad.exe, awesomiumprocess.exe and planetside2.exe).

But I guess you've probably already tried this?
