title: How to handover file location to custom action method WIX
body: <p>Suppose I have a custom action for my Wix Installer that needs the path from a file:</p>
  <pre><code>public static ActionResult AddUsbLanCertificate(Session session, string path)
  {
  
      //do something e.g. File.Copy(path, dest);
      return ActionResult.Success;
  }
  </code></pre>
  <p>How can I tell this CustomAction where this file is located, How I can handover the path?</p>
