if youre having the crash to desktop when selecting me3 and couldn't understand the readme instructions i figured it out:

1.download BSA unpacker

2.extract all the files to any location

3.go to meshes>solidsnakedavid>masseffect3>jackrace and remove "jackhairnnew1.nif"

4.if you've already placed the bsa and esp into the data folder, just delete the "Mass Effect 3 - Jack Race.bsa" file(dont delete the .esp)

5.place the textures and meshes folder into the data folder of fallout as well as the .esp if you haven't already

6.get in game and select me3 jack

done!
