Windower documentation / Square Enix third-party-program policy
Windower is a named community framework that loads Lua addons and plugins through a launcher profile. Its documentation explicitly identifies FINAL FANTASY XI. Square Enix’s game-specific support policy prohibits third-party programs that affect gameplay, so this reference is not an approved installation recommendation.
