title: WIX public properties displayed on the UI
body: <p>We have an installer created using WIX.  As part of this install we would like to show the currently selected installation path.  I thought this would be much easier than it is, apparently.  I have tried using the a public property "INSTALLDIR" (I know we're not using Installshield, this value is a directory ID.) </p>
  
  <p><code>&lt;Directory Id="INSTALLDIR" Name="AcmeInc"&gt;</code></p>
  
  <p>I can also see where INSTALLDIR gets set when running the install </p>
  
  <p><code>MSI(EC:6C) Dir (target): Key: INSTALLDIR , Object: C:\Program Files\AcmeInc\</code></p>
  
  <p>but when I try to show this on the UI using a Text attribute I get "<code>...\.</code>" which doesn't even look to be a relative path.  </p>
  
  <p>I know there has got to be something simple I'm missing here.</p>
