SKSE Plugin Loader 2.2.6 Error: Causes & How to Fix It

The SKSE (Skyrim Script Extender) Plugin Loader 2.2.6 error is a common issue that occurs when there is a mismatch between your Skyrim version, SKSE, and SKSE-dependent mods. This error typically manifests as a message stating:

“A DLL plugin has failed to load correctly. If a new version of Skyrim was just released, the plugin needs to be updated.”

Below, we break down the root causes, troubleshooting steps, and solutions to resolve this error.

Common Causes of SKSE Plugin Loader 2.2.6 Errors

1. Game Version Mismatch

SKSE 2.2.6 works only with Skyrim SE/AE version 1.6.1170 or 1.6.1179. Check your executable:

• Right-click SkyrimSE.exe > Properties > Details tab.
• Use this table to verify:

2. Outdated or Incompatible DLL Plugins

If your logs mention specific DLLs like CommunityShaders.dll, OpenAnimationReplacer.dll, or Underwear.dll, they are likely built for a different SKSE version or outdated entirely.

3. Incorrect SKSE Installation

SKSE files must be placed directly in the Skyrim root folder (where SkyrimSE.exe is located). Make sure you have:

• skse64_loader.exe
• skse64_steam_loader.dll
• skse64_1_6_1170.dll (or corresponding version)

4. Missing Engine Fixes Part 2 DLLs

If SKSE or your game crashes without loading properly:

• Check for presence of: d3dx9_42.dll, tbb.dll, tbbmalloc.dll
• These should be manually placed in the game’s root folder.

5. Missing Dependencies (VC++ Redistributable)

SKSE plugins often require the Microsoft Visual C++ Redistributable (2019 x64). Install from Microsoft’s site and restart.

6. Conflicting Mods (DAR vs OAR)

Don’t install Dynamic Animation Replacer and Open Animation Replacer together. OAR is the updated, supported choice.

Step-by-Step Fixes for SKSE Plugin Loader Errors

1. Match Skyrim and SKSE Versions

Before applying fixes, ensure your game and SKSE versions are compatible.

• Confirm Skyrim version via SkyrimSE.exe Properties > Details.
• Download correct SKSE build from https://skse.silverlock.org
• Steam and GOG versions have separate builds.

2. Update or Remove Problematic Mods

If the error message names specific .dll plugins, they’re likely outdated or broken.

• Google the DLL (e.g., FormListManipulator.dll) to find the mod.
• Check Nexus Mods for a version that supports AE (1.6.1170+).
• If unsupported, remove or disable the mod.

3. Install SSE Engine Fixes Properly

Ensure both parts of SSE Engine Fixes are installed correctly to avoid plugin crashes.

• Part 1: Use mod manager to install.
• Part 2: Manually extract the 3 DLLs to your Skyrim root folder:
  • d3dx9_42.dll
  • tbb.dll
  • tbbmalloc.dll

After installation:

• Launch Skyrim via skse64_loader.exe
• Check d3dx9_42.log to confirm plugin loading status.

4. Install VC++ Redistributable (2019 x64)

Install this dependency to ensure proper plugin functionality. Download here: Microsoft VC++ Redistributable

5. Whitelist SKSE in Antivirus

To prevent antivirus from blocking mod files or SKSE.

• Add SkyrimSE.exe and skse64_loader.exe to your exception list.

6. Avoid Conflicting Mods

Mod conflicts are common and often result in load errors or CTDs. Disable one of the following if installed together:

• DAR and OAR
• Mods like Papyrus Extender with Engine Fixes (unless configured correctly)

Extra Troubleshooting Tips

Crash at Main Menu (CTD)

Fix crashes after the Bethesda logo with these solutions:

• Check for broken INI files or incompatible shader mods.
• Increase MaxStdio in EngineFixes.toml to 8192
• Ensure Animation Limit Crash Fix is not conflicting with Engine Fixes.

DynDOLOD Cow Bug

A giant cow near Whiterun usually means DynDOLOD was installed incorrectly.

• Reinstall it using the official DynDOLOD instructions.

Vortex Users: Manual Fix Reminder

Vortex does not automatically install Engine Fixes Part 2. You must place the DLLs in the root folder yourself.
