1.0 already has an installer version
https://www.mediafire.com/?daar6wsev4skwyb, before you do these three steps you have to create an empty folder in napoleon/data and name it acw
- Download and save the acw.rar to the /steamapps/common/napoleon/data/ folder.
- Open the rar and press the "Extract to"-Button (NO "Extract here")
- Target folder should be: "(...)/steamapps/common/napoleon/data/acw
The launcher to start the game is now in the acw folder you created, double click and play. Basically when you launch the game all those files in acw folder move to your data automatically and then back when you exit game, so that you can play vanilla napoleon.
