This will probably be the only version i will release as i want to work on another mod for the same game. There should not be any bugs but if there is then please inform me and i will fix it.
Backup your current Napoleonic Wars game incase you wish to revert back.
Locate C:\Program Files (x86)\Steam\steamapps\common\MountBlade Warband\Modules\
and replace Napoleonic Wars with the new one in the mod folder
