title: Installation using wceload and /noaskdest /noui
body: <p>I am installing cab file of my application using wceload.exe. When my application already exists it gives message "My application is already installed.Reinstall?" How to avoid this message? Cab file installation launches when I use            </p>
  
  <pre><code>ProcessStartInfo info = new ProcessStartInfo();
  info.FileName = @"\windows\wceload.exe";
  info.Arguments = "\\My_Installer.cab";
  Process proc = new Process();
  proc.StartInfo = info;
  proc.Start();
  proc.WaitForExit();
  </code></pre>
  
  <p>When I use </p>
  
  <pre><code>info.Arguments = "\\My_Installer.cab /silent"; 
  </code></pre>
  
  <p>or </p>
  
  <pre><code>info.Arguments = "/noaskdest /noui \\My_Installer.cab"; 
  </code></pre>
  
  <p>nothing happens. What am I doing wrong?</p>
