title: EXE silent installation
body: <p>I have following PowerShell script to install application without user intervention:</p>
  
  <pre><code>Start-Process -FilePath "C:\Temp\UpgradeClientInstaller\setup.exe" -ArgumentList "/S /v/qn"
  </code></pre>
  
  <p>by giving <code>/s</code> in argument list, it should install silently without user intervention but a popup is showing <a href="https://i.stack.imgur.com/UGhwc.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/UGhwc.jpg" alt="powershell issue"></a></p>
  
  <p>Even I try with <code>winrar.exe</code> and <code>zip.exe</code> files giving the same result. Is this right way to do?</p>
