Okay, Im curious, just what is the point to the desktop updaters?
The desktop shortcut will run a utility that creates/updates the primary files that are loaded by v4.1 cr2. You only need to run it if there are any new secondary files that need to be added to the primary files (such as characters or clothing that also take advantage of the new ExP technology). Content Developers will need to tell users when their content uses this ExP technology.
