If needed, rollback to an older patch, using Steam Beta tab. Never install mods in Steam directory (ex: C:\Program Files (x86)\Steam\SteamApps\common\Crusader Kings II\mod), as mod would not be properly loaded.Ĭheck in the mod description the CK2 version compatible with the version of the mod. Mac: ~/Documents/Paradox Interactive/Crusader Kings II/mod/.Linux: ~/.paradoxinteractive/Crusader Kings II/mod/.Windows: ~\Documents\Paradox Interactive\Crusader Kings II\mod\.Mods can be downloaded and installed manually from User Modifications sub-forum ( game registration needed), or automatically from Steam Workshop.
