FNIS for modder error 2012 issue

[alphafr]

So I followed the given tutorial to remove some unwanted animations in a animation pack in order to stay below the 10k animation limit but I somehow can't run FNIS for modder to regenerate the behavior file

 

Tried to run as admin and without anti-virus to no avail

 

Happen on FNIS list.txt I removed a lot of animation (bakafactory human & creature pack and anub animation pack)

 

Edit 1: Seems only certain pack's FNIS .txt file have that issue

 

Edit 2: Even unmodified FNIS can't generate anything from those, no clue why though
