This is just to note that the install path has changed from the original version. If you don't correct manually, you will have both sets installed.
Original Install Path: ...\My Documents\SimCity 4\Plugins\CSX\CSXLots\CSX Entrances
Updated Install Path: ...\My Documents\SimCity 4\Plugins\CSX\CSXLots\Entrances
Either a cleanitol file could be provided or the install path corrected to overwrite the originals. Otherwise, folks will have to remember to delete the originals manually if they have them...
I shall correct the installer and update.
Edit: done and updated
