I have a similar problem.
I'm trying to install EETand some mods, using EET MOD SETUP TOOLS.
After several unsuccessful attempts, I managed to solve almost all the problems.
Currently the only mod I have problem with is SCS.
I have given up (such a pity!) on installing the AI components (AI initialization always fails) and the components concerning the spells
(actually the installation happens without problems, but I have read that it can generate conflicts and can be the cause
of the failure of installing other mods), relying on alternative mods.
The only component I would not want to give up is the one concerning the shapeshifter ("MUTAFORMA" in Italian),
but unfortunately installation continues to fail.
This the error message:
Any suggestion? Thanks!
