REL/Relocation.h(567): failed to open file Error

[CHULiving21]

Hello,

Trying to launch skse64 loader will give me the error noted below.

Enginefixes.dll
REL/Relocation.h(567): failed to open file

I have Skyrim SE version: 1.6.1170
I have SSE Engine Fixes (Part1)  6.1.1 and 5.9.1 (and tried both at the same time in addition to individually)
SSE Engine Fixes (Part2) is 2020.3 and the three .dll files have been placed in the Skyrim folder where the game launcher is located.

Address Library All in One Version 2 and 11 (tried one at a time and simultaneously)

SKSE64 version 2.2.6

SSE Engine Fixes-Modified .toml File Only for SSE v1.6.1170 (v6.1.1.3)

Any suggestions on how to fix this? I've checked the enginefixes.toml document and the "enable acheivements with mods" and "save screenshots" functions are turned off. I've also tried running skse64 in admin to see if that would help.

I have the mods I'm using narrowed down to which ones rely on skse64, and I'll start disabling them one by one to see if they are interfering with the engine somehow. Starting Skyrim SE the normal way allows it to function as intended.

I'd appreciate any ideas. I've searched for solutions, but wasn't able to find answers. Would it help if I bought the new dlc upgrade?

Well, if anyone should come across this and learn something from it, I've figured it out. Reinstall everything and go line-by-line with the mods. As of right now, I think the culprit is either the complete alchemy and cooking overhaul or the dual-casting fix. Or both. Trial and error is a merciless taskmaster.

Use only ONE Address Library (the latest that matches your game version).  Make sure that the .toml for Engine Fixes is in its proper place (...steamapps\Skyrim Special Edition\Data\SKSE\Plugins.
