title: Installers: WIX or Inno Setup?
body: <p>I'm comparing these two tools.  The impression I have is:</p>
  
  <ul>
  <li>Inno Setup does not produce an MSI, but can do everything WIX can do</li>
  <li>WIX does produce an MSI, but has a steep learning curve</li>
  </ul>
  
  <p>Do you agree with this characterization?  What other differences are there?  How does <a href="http://www.codeproject.com/KB/install/WixSharpArticle.aspx" rel="noreferrer">WIX#</a> shake-up this story?  Since Inno Setup does not use the windows installer, does it have difficulty with uninstalls?  Can Inno Setup, upon command, downgrade an installation to an earlier version - or can it only install / upgrade applications?</p>
