title: Silent Administrative Install - Specifying an installation directory
body: <p>I'm currently trying to add some testing functionality into our builds, and in order to do this I need to be able to perform an administrative install, silently. However, I need to be able to specify the location that it installs too, as the default is on the company-wide network which is no use.</p>
  
  <p>I was wondering if there was a way to specify the installation directory through parameters for this type of operation, and if so how?</p>
  
  <p>Many thanks,
  Chris</p>
