Nucleus Coop fix for Elden Ring Nightreign which broke after the Windows update of April 14th, changing how DLLs are loaded. This fix probably works on many others games in Nucleus Coop

Nucleus Coop Nightreign Fix for Windows Update.md

Guide

This is my fix for Nightreign on Nucleus Coop: https://drive.google.com/file/d/1BLAyDbZMDoyI5CrxOsD1dOnNnUMY_yac/view?usp=sharing

In the zip file, you will find 3 files, the only one you are interested into is xinput1_4.dll, the others are in case you want to compile the DLL by yourself (you shouldn't trust random people on the internet giving you DLLs, I give you the opportunity to compile from source code).

This guide assumes 2 things:

• Your OS is 64 bit (Windows 11 is 64 bit on the newer updates)
• Your nucleus installation is in C:\nucleus. It's fine if it's somewhere else, but through this post I'll refer to it as C:\nucleus

Installation

Go into C:\nucleus\utils\XInputPlus\x64 and rename the file you find here called xinput1_3.dl_ to xinput1_3.dl_.bak (this is just a backup copy in case something goes wrong)

Download and extract the zip file attached to this post Open the directory that came out of the zip file and rename xinput1_4.dll to xinput1_3.dl_ Copy the renamed file xinput1_3.dl_ into C:\nucleus\utils\XInputPlus\x64

Close and reopen Nucleus Coop Right click on Nightreign in Nucleus Coop and press Delete Game Content Folder (optional, this is just to make sure it works)

Start the game with Nucleus Coop
