Hello, just to help if others have the same problems, here are some glitches during my new installation:
Vienxay NPC for BG1EE (Vienxay (New)) was not installed due to errors"
Aura NPC (Aura) was not installed due to errors.
I did install them manually with no error message anyway.
ERROR: Unix.Unix_error(20, "stat", "AjocMod/spl/spwi966.spl")
I couldn't install it even manually.
Safana in Amn mod -
The EET install couldn't find it because it was in a master file after extracting and not fully developped in the BG II EE folder.
I could install it anyway without trouble.
