title: Installshield Silent Uninstall not working at Command Line
body: <p>We have an older app from 2006 we'd like to uninstall at the command line using group policy, but I can't get a silent uninstall to work.</p>
  
  <p>This works.  Of course I need to click Next to uninstall:</p>
  
  <pre><code> "C:\App\Setup.exe" /uninst
  </code></pre>
  
  <p>But this does not.  I see an hourglass for a couple seconds but the app is not uninstalled.</p>
  
  <pre><code> "C:\App\Setup.exe" /uninst /s
  </code></pre>
  
  <p>I also unsuccessfully tried some VBScripts.  They find the app listed but the uninstall fails.  I'm not too familiar with how this process is supposed to work.</p>
