failed due to the following error: 800704a6 while trying to read data from a text file in teamcity

I am running some test cases using teamcity. It is saving the data on a textfile successfully but when I try to read that data from same location it is giving the following error

SetUp method failed. System.Runtime.InteropServices.COMException : Creating an instance of the COM component with CLSID {0002DF01-0000-0000-C000-000000000046} from the IClassFactory failed due to the following error: 800704a6. at WatiN.Core.IE.CreateNewIEAndGoToUri(Uri uri, LogonDialogHandler logonDialogHandler, Boolean createInNewProcess) at WatiN.Core.IE..ctor()

and replace the saved data with System.String[]. Also tried giving all permisssions to the user but still cant fix it. Please help.

I also have enabled most of the IE8 settings. Any idea what is causing this

Not sure if this has been resolved or not but I was having the same error in 2 different test fixtures 1 written in C# the other written in VB.NET.

For the C# fixture all I need to do to resolve the issue is when I create a new instance of WatIn.IE, I added the second parameter to: IE var ie = new IE(url, true) The "true" tells WatIn to "createInNewProcess" which opens the next IE in a new process.

This, however, did not work for the test fixture written in VB.NET for some reason. For this fixture I had to call a method in one of our C# libraries to force an IE closure in each Tests "TearDown" method. The following C# code did the trick:

public static void CloseInternetExplorers()
{
  var processes = from process in Process.GetProcesses()
                  where process.ProcessName == "iexplore"
                  select process;

  foreach (var process in processes)
  {
    while (!process.HasExited)
    {
      process.Kill();
      process.WaitForExit();
    }
  }
}

Reboot the machine

There are windows updates getting in the way of instantiating new COM objects.

Error code 800704a6 according to a few forums, and this ServerFault posts means ERROR_SHUTDOWN_IS_SCHEDULED
