Hi, Here is an updated version with the following fixes/improvements: * correctly set registry key for TYP file * set registry key for index files only when present * possibility to use own template for installer script (details below) * installer localization (English and French at the moment) To customize the installer script one need to create a resources directory with: * installer_template.nsi to customize the installer script. There are four important lines that the file should have for mkgmap to generate the script properly: * ; INSERT_DEFINES_HERE should be near the beginning of the file, mkgmap will define a certain number of variables that are used later in the script * ; INSERT_ADDED_FILES_HERE mkgmap will generated the list of files to be packaged in the installer * ; INSERT_REGBIN_HERE mkgmap will add a line for the family_id registry key. This is binary and cannot be taken care of in the defines unfortunately * ; INSERT_REMOVED_FILES_HERE mkgmap will generated the list of files to be uninstalled by the uninstaller * license_template.txt this file will be displayed by the installer in the license page the default files are provided in the examples directory of the mkgmap installation for convenience Thanks, N.
