title: Open txt file in wix when clicking btn
body: <p>I have a wix project to which I added a custom window that checks the dependencies needed to run the app. This window comes up right after the License Agreement. Everything works fine, the dependencies are checked through custom actions and in case they are not fulfilled hyperlinks to official websites appear if the windows installer is above version5. </p>
  
  <p>In case of a lower version I would like to click on a btn "Show dependencies" and to show the txt file with the links. I have the custom action below that open notepad and the property that contains the file.</p>
  
  <p>Code:</p>
  
  <pre><code>&lt;Property Id="FXDEP" Value="$(sys.CURRENTDIR)\Resources\Files\FxDependencies.txt" /&gt;
  &lt;Property Id='NOTEPAD'&gt;NOTEPAD.EXE&lt;/Property&gt;
  &lt;CustomAction Id='LaunchDependencies' Property='NOTEPAD' ExeCommand='[FXDEP]' Return='asyncNoWait' /&gt;
  </code></pre>
  
  <p>The problem is that on the dev machine it works since it finds the path, but on other of course it fails.
  How should I tell wix to maintain this file and open it?</p>
  
  <p>I tried putting the file into </p>
  
  <pre><code>&lt;Binary Id="FxDependencies.txt" SourceFile="$(sys.CURRENTDIR)\Resources\Files\FxDependencies.txt" /&gt;
  </code></pre>
  
  <p>but the custom action does not recognize it.</p>
