I don't get that option at all. I just try to enable the SkyUI mod on NMM and it says: Problem #1:-----------The Skyrim Script Extender (SKSE) is not installed. Solution:Get the latest SKSE version from 'http://skse.silverlock.org/' and install it. Is this because I downloaded it on Steam? On the nexusmods website for SkyUI, the creator of the mod said it cold work with Steam as well.
