In a testlist execution, there are frequent times where a test in the testlist fails because of this exception: '3/20/2014 11:10:38 AM' - System.ApplicationException: Exception thrown attempting to launch Internet Explorer. Please make sure Internet Explorer is properly installed and you are able to launch it. ---> System.TimeoutException: Wait for condition has timed out at ArtOfTest.Common.WaitSync.CheckResult(WaitSync wait, String extraExceptionInfo, Object target) at ArtOfTest.Common.WaitSync.For[T](Predicate`1 predicate, T target, Boolean invertCondition, Int32 timeout, WaitResultType errorResultType) at ArtOfTest.Common.WaitSync.For[T](Predicate`1 predicate, T target, Boolean invertCondition, Int32 timeout) at ArtOfTest.Common.WaitSync.For[T](Predicate`1 predicate, T target, Int32 timeout) at ArtOfTest.Common.Win32.Connector.Attach(IntPtr& handle, Boolean findTabWindow) at ArtOfTest.WebAii.BrowserSpecialized.InternetExplorer.InternetExplorerActions.LaunchNewBrowserInstance(Int32 timeout, ProcessWindowStyle windowStyle, String pipename) --- End of inner exception stack trace --- at ArtOfTest.WebAii.BrowserSpecialized.InternetExplorer.InternetExplorerActions.LaunchNewBrowserInstance(Int32 timeout, ProcessWindowStyle windowStyle, String pipename) at ArtOfTest.WebAii.Core.Manager.LaunchNewBrowser(BrowserType browserToLaunch, Boolean waitForBrowserToConnect, ProcessWindowStyle windowStyle, String arguments) at ArtOfTest.WebAii.Design.Execution.ExecutionEngine.InitializeWeb(ExecutionEngineCreateParams initParams) at ArtOfTest.WebAii.Design.Execution.TestExecuteProxy.CreateAndInitializeEngine(Test test, ExecutionEngineCreateParams cp) at ArtOfTest.WebAii.Design.Execution.TestExecuteProxy.ExecuteTest(ExecuteTestCommand command) ------------------------------------------------------------ Is there something that can stop this from happening? I have Win 8.1 and IE 11.
