Can I run Mount and blade Napoleonic wars?

Its downloadable, first you need Mount and blade warband (like 20$ on steam unless you get the bundle) download it. Napoleonic wars is a DLC for multiplayer (and mods) you then download that and start up mount and blade warband, when the menu pops up it will have a bar that says native, change that to napoleonic wars then your good to go. Warning its fun. I prefer commander battle as you can command your own troops and face against other players and there troops… Also if you plan to join one of the regiments(basically clans) they usually have a strict set of rules and *training*(they teach you how to play as a regiment)

Ok, cool. Where do I start to download the game?
