Checked everything, but still getting "An attempt to work with a closed driver" (DDT - ExcelDriver)!

I have installed Microsoft Access Database Engine 2010 already. Using TestComplete 12.3 and Excel 2013. I am still getting "An attempt to work with a closed driver" error! Here is my script (JavaScript) -

try
    {
      DDT.ExcelDriver("c:\\femalePatients.xlsx", "Female_E");
  
      
            while (!DDT.CurrentDriver.EOF())
	    {
	      if (DDT.CurrentDriver.Value("Name") == "Lizzie Hari")
	        {
	          New_Patients.createPatients();
	        }
	      DDT.CurrentDriver.Next();
	    } 
    } 
    
    
    
    catch(exception)
    {
      Log.Error(exception.message);
    }
  DDT.CloseDriver(DDT.CurrentDriver.Name);

I even restarted the computer to make sure DDT drivers not running, still no go!

Help is much appreciated.
