Repost from the FNIS nexus forum: A question. Im using MO 1.3.7, run fnis 5.5 with the correct patches and do this since a long time. Never bothered to move the files out of the overwrite folder, instead deleted everything and run fnis again, if anything changed with my animations. Today I deceided to put more significance on an empty overwrite folder so I clean overwrite, run fnis, create mod FNISoutput from the overwrite files and put this mod into loadorder making sure nothing overwrites the fnis files in it. I followed https://wiki.step-project.com/Fores_New_Idles_in_Skyrim to be sure that I dont screw up. I log into game and get the following message: FNIS has not been successfully run or installed. SL currently requires a working install of FNIS 5.1.1 <snip> Ingame animations of SL dont work. But why? Removing the created FNIS mod, updating behaviour and starting skyrim with files in overwrite folder and no errormessage and everything seems alright. I did google for fnis+mo but didnt found anything useful btw.
