I've extracted the BSA files and installed the mod with Wrye Bash and there are no conflicts. I didn't checked the ESP with TE5EDIT for conflcits because I don't know how to check this. :|
Anyway, I'm using the mod from the begining and no issues so far.
Link:Â https://www.nexusmods.com/skyrim/mods/30533/? IÂ really like this mod. It changes the FOV so you're literally face to face to an NPC when talking to he/she. I think it's immersive specially if you play on 3rd person camera as I do. Would it me safe to use it in a STEP installation? Thanks!
