"An exception occurred within the TtcUtilsManager handler of the TtcTestEngineEventDispatcher event: Interface not supported." I am trying to execute an example from the TestComplete Help, the example is about using timers: the link to example is http://support.smartbear.com/viewarticle/69564/#ID0EVFAC // Unit1 function Main() { // Create a 30-second timeout timer Utils.Timers.Add(30000, "Unit1.TimeoutTimer", true); // This loop will be stopped after about the 30th iteration for (var i = 1; i <= 100; i++) { Log.Message(i); Delay(1000); } } function TimeoutTimer() { Log.Message("The test timeout has been reached... Stopping the test."); //Runner.Stop(); } Please hint how can I fix this problem. I use TestComplete 10.3 Re: An exception ... Interface not supported. I have sent the request to the official support Re: An exception ... Interface not supported. Now I am trying to update TC from 10.30 to 10.60. After computer reset my scripts do not work because TestComplete no more recognizes controls as "Open Application". If I return back 10.30 it works. What shall I set up in 10.60 or I cannot update testComplete?
