To uselace the MapInstaller.bat file in an empty folder. Unzip the map file(s) in that folder. Then doubleclick on MapInstaller.bat and the files will be installed to the appropriate folders. The reason for the empty folder is that all of the file are copied in one operation and the unecessary ones with certain file extensions are deleted afterwards. This way no unecessary files are copied over and maybe not deleted in the process.You can also install creature mind files with this method.
