Windows service is not able to start

Hi,

I have created sample windows service using C# and have installed on my development machine(windows 7 enterprise ,64 bit)But i got the error A timeout was reached (30000 milliseconds) while waiting for the Service1 service to connect. while trying to start the service .then i have addedd the regidtry key ServicesPipeTimeout DWORD value to 60000 in theControl key and restarted the machine.Now i am getting  timeout was reached (60000 milliseconds) while waiting for the Service1 service to connect.I am not able to figure out what is the cause for this issue.

 public Service1()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
             
       _timer = new System.Timers.Timer(10 * 60 * 1000); 
           _timer.Elapsed += new   
        System.Timers.ElapsedEventHandler(timer_Elapsed);

        }

 private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
          Process();
            
        }

  public  void Process()
        {
           The below process is comment out to resolve the starting issue
        //BusinessLayer.ProcessFile.ProcessFiles();            
           
        }
 protected override void OnStop()
        {
        }

Please advise what could be the issue ?.Thanks in advanse.
