.Net下 自动执行MSI和EXE文件

  var tempDir = @"D:\UploadFiles\SCADASetupWix.msi";

                start.CreateNoWindow = true;
                Process.Start(start);//.WaitForExit()

  Process prc = new Process();
            try
            {
                prc.StartInfo.FileName = @"C:\Users\Administrator\Desktop\SCADA\setupok.exe";
