Run the LME3 Setup.exe and install it in your "napoleon total war" folder (not the data folder), then follow the included instructions (contains all frequently updated LME mod files). Accept all prompts for overwrite as no vanilla files are overwritten without making an automatic back-up. A copy of the LME3_readme.rtf is located in your "napoleon total war" folder after installation and can be viewed with wordpad. The LME3 mod launcher requires Microsoft .NET Framework 4.0 installed and it can be downloaded from here. If you have played other mods that uses a mod launcher you may already have .NET Framework 4.0 installed. All files necessary to play LME3 with all the submods are now installed and you PC is setup to play the mod.
