Slient Mode (in Task Scheduler command-line) is not working in Test Complete 11

Previously i was using Test complete v10 and i had scheduled a daily test run through windows schedule task. This worked very fine as it automatically trigger test complete at that time, continue testing and when testing is completed, the Test complete is closed automatically (since i set Slient mode, the test complete will not wait for my input in the Save window).

Ever since i upgraded to Test Complete v 11. i think the test complete is not supporting slient mode. After the schedule test is completed , the test complete is not closing by itself and wait for the user input. Since there is no user input, the test complete remains open and next day test could not be triggered.
