title: Automated MSI installation
body: <p>What is the best way to automatically install an MSI file or installer .exe? We want to do some automated testing from our build system on the installed copy of the product. Our installer has the usual license acceptance screen, install location, etc.</p>

  <p>As FryHard pointed out there are two options in particular that seem handy:</p>
  
  <ul>
  <li>"/quiet" - no use interaction</li>
  <li>"/passive" - process bar only, unattended mode</li>
  </ul>
