title: Silent install parameter ignored, InstallShield 2009
body: <p>I've just inherited an InstallShield 2009 project from a guy who left (oh joy) and am trying to get the setup.exe to run in silent mode.  The project is a Basic MSI project and according to the documentation, I should be able to specify the /s switch combined with /v/qn to make the installer and MSI process silent.  However, when I do this, the process shows all the dialogs as normal.  I've tried generating an answer file with the /r switch, but this fails to produce any sign of a setup.iss any where (I checked the windows folder, which is where it apparently goes).</p>
  
  <p>Why would the process be ignoring the silent commands?  I can see nothing in the install log that indicates a problem...  The command line I am using is this:</p>
  
  <p>setup.exe /s /v/qn</p>
  
  <p>I've tried various combinations of lower and uppercase to no avail.  Any advice would be appreciated.</p>

  <p><strong>Edit:</strong></p>
  
  <p>I've also tried:</p>
  
  <p>setup.exe /s /v"/qn"</p>
  
  <p>Which did not work also.</p>
  
  <p><strong>Edit 2:</strong></p>
  
  <p>It might be worth pointing out that the installer is performing and upgrade from a previous version of the product to a newer version.  The first dialog that pops up is the "extracting msi" dialog followed by the "welcome to upgrade" dialog.</p>
