            try
            {
                ServiceController sc = new ServiceController("YottaMark Code Dispenser");
                if ((sc.Status.Equals(ServiceControllerStatus.Stopped)))
                {
                    sc.Start();

                    MessageBox.Show("Starting the  YottaMark Code Dispenser");
                }
                MessageBox.Show("Started the YottaMark Code Dispenser");
            }
            catch (Exception Ex)
            {
