Problems with installing components of the Paradise Halls mod

[Themufik]

This is my second attempt to install this mod — I even bought the game legally this time, haha.
I recently downloaded a clean version of Skyrim Special Edition.
Created a new profile in Mod Organizer, enabled it, and started installing the required components.

Everything was going fine until I got to the FNIS part — that’s when the problems started.
FNIS components wouldn’t install or update properly.
I kept getting various errors.
I tried switching the execution environment to the new FNIS, changed installation paths, and so on — but nothing helped.

I really need some help figuring this out.

 

I’d really appreciate any help or advice. Thanks in advance!
