                return false;
            }
            return true;

Answering my own question ,

Its because of the path i gave in the process ,

  ProcessStartInfo psi = new ProcessStartInfo(@"Windows\wceload.exe", "/nodelete \"Program Files\\DeviceApplication3\\DeviceApplication.CAB\"");

        Process proc = Process.Start(psi);
