No way. EWA is a collection of mods that, taken together, bring about global changes. No single global mod can be compatible with another global mod; it's strange to try to fit a horse into a car's interior. Install a second copy of the game in a different folder and install the mod you're interested in there. It's a different matter that some specific, non-global mods can be tried to be extracted from EWA and mixed in here if there are people willing to do it.

Downloaded the mod, installed it on the Steam version (it's in English there). Downloaded the Russian language pack, but it doesn't want to localize the game; it says that the game is not installed, which prevents me from playing with the Russian language. How can I fix this?
