title: How can I read custom action's executable output in WiX?
body: <p>I'm making MSI installer in WiX. During installation I want to run an executable from a <a href="http://wix.sourceforge.net/manual-wix2/wix_xsd_customaction.htm" rel="nofollow">custom action</a> and get its standard output (not the return code) for later use during installation (with <a href="http://wix.sourceforge.net/manual-wix2/wix_xsd_property.htm" rel="nofollow"><code>Property</code></a> element, supposedly).</p>
  
  <p>How can I achieve it in WiX (3.5)?</p>
