title: Free MSI Authoring tools
body: <p>Are there any free / open source tools that can be used to create an advanced MSI installer.</p>
  
  <p>I've found the <a href="http://www.installsite.org/pages/en/msi/authoring.htm" rel="nofollow noreferrer">following list</a> of MSI authoring tools, however I know very little about MSI technology and its hard to tell from that list which of those tools can actually be used to create new MSI installers from scratch (as opposed to simply viewing or editing existing installers)</p>
