title: Install4j installer fails with internal error for Mac OS
body: <p>I have built an installer using the latest Install4J. On the Mac OS, it fails to install with the following message: "An internal error has occuerred (error code: launch path not accessible)". </p>
  
  <p>The same installer for other platforms (Windows 32/64, and Linux) work fine. Has anyone else seen this and know how to fix it?</p>
