title: Pushing out MSI files
body: <p>I have a product which has been traditionally shipped as an MSI file.  It is deployed through some sort of SMS push to thousands of desktops by our various clients.  The software we use to create these installers is getting long in the tooth and we are looking to replace it.  We have already standardized on InstallAnywhere for most of our products as we support many operating systems.  Unfortunately InstallAnywhere cannot produce MSI files.  </p>
  
  <p>I am wondering if it is required that SMS use MSI files or if it can handle other installer types (.exe).  If not, are there any open source programmes for creating MSI files?  </p>
