IzPack - Desktop Shortcut on Windows - Not Working

I'm trying to use IzPack to install my program and I'd like to add Desktop Shortcuts to the installer, here is the documentation/instructions from the IzPack website.

http://izpack.org/documentation/desktop-shortcuts.html

However, the below XML files, when compiled, only create a blank screen in the installer that hangs when you try to click "Next" to go past it. Here's what the screen looks like when running on Windows 7 - 64 bit.

Here is my install.xml and shortcutSpec.xml files.

install.xml

<?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
