I have uploaded a new PortablE beta archive with a very small fix (almost cosmetic):

* When the installer deletes obsolete modules, it will no-longer fail to delete a couple of folders (which was harmless but might have worried some people).
* A small 'bonus' is that the installer will now delete a few obsolete modules that I had previously overlooked.

Users who have already installed the latest release of PortablE do NOT need to download it again!
