Ah - thanks, the Mod folder shouldn't be too hard to find.
I have downloaded the War of 1812.exe file from the first post. When I run it, it tells me to buy the Napleonic War Module (which I have).
I have been able to connect to a regular Napoleonic server. When I re-run the setup I get the same error.
I have tried a couple of ways of extracting the files from the .exe (assuming it's a self-extracting archive). I've had no luck so far. Usually 7-Zip handles that OK, but not in this case.
Are the mod files available in a non-exe file somewhere? Or do you have any tips on extracting them?
Thanks in advance,
