TeamSpeak 3 NOT starting

When i try to run the program nothing happens, after a few seconds the windows7 waiting clock stop, but TS3 doesnt open not even in the taskbar or sth. I checked the process in the task manager and sometimes there's one running, ts3_win64 client but the program still doesnt appear. I tried repairing the install, reinstalling etc but the problem persists
