Call Of Duty Black Ops 3 The Additional Dll Could Not Be Loaded Top May 2026

If the C++ fix does not work, the issue may be related to controller support drivers. Steam’s internal controller support can sometimes conflict with the game’s native DLLs.

Troubleshooting: "The Additional DLL Could Not Be Loaded" in Call of Duty: Black Ops 3

If you’re trying to jump into a round of Zombies or Multiplayer in Call of Duty: Black Ops 3 only to be stopped by the error "The additional DLL could not be loaded," you aren't alone. This specific error is a common headache for PC players, usually appearing right at launch or after a game update.

In most cases, this isn't a sign of a broken GPU or a dying hard drive. Instead, it’s typically a software conflict, a missing system file, or an overzealous security program. Here is a comprehensive guide to getting your game back up and running. 1. The Most Common Fix: Verify Integrity of Game Files

Since BO3 relies on a complex web of Dynamic Link Libraries (DLLs) to function, a single corrupted file can trigger this error. Steam has a built-in tool to find and replace these. Open your Steam Library. Right-click on Call of Duty: Black Ops III. Select Properties > Installed Files. Click Verify integrity of game files.

Wait for the process to finish. Steam will automatically redownload any missing or corrupted DLLs. 2. Disable Antivirus and Windows Defender

The "Additional DLL" error is frequently a "false positive" caused by antivirus software. Your security program might see a specific game file (often related to the Steam API or anti-cheat) and quarantine it, preventing it from loading.

Temporary Fix: Disable your antivirus and try launching the game.

Permanent Fix: Add the entire Black Ops 3 installation folder to your antivirus Exclusion/Exception list.

Default Path: C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops III 3. Reinstall DirectX and Visual C++ Redistributables

DLLs are essentially "instruction manuals" for your computer. If the standard Windows manuals (DirectX and Visual C++) are outdated or missing, BO3 won't know how to load its own additional files.

Visual C++: Go to the Microsoft website and download the latest x64 and x86 Redistributables. Many users find that repairing the 2010, 2012, and 2015 versions specifically fixes BO3.

DirectX: Ensure your DirectX is up to date via Windows Update or the DirectX End-User Runtime Web Installer. 4. Check for Conflicting Software (The "Overlay" Problem)

Certain third-party applications that "hook" into your game can prevent DLLs from loading correctly. Common culprits include: MSI Afterburner / RivaTuner Statistics Server Discord Overlay EVGA Precision OBS (specifically Game Capture mode)

Try closing these applications completely before launching the game to see if the conflict resolves. 5. Issues with Workshop Mods

If you play Custom Zombies, a corrupted mod might be the "additional DLL" failing to load.

Try unsubscribing from your most recently added Workshop items.

Alternatively, go to the zone folder in your BO3 directory and see if any recently added mod files look incomplete or out of place. 6. The "LPC" Folder Fix (For Advanced Users)

Some players have found success by navigating to the game's installation folder and looking for the LPC folder.

Navigate to: SteamLibrary\steamapps\common\Call of Duty Black Ops III\lp

If this folder is empty or missing files, it can cause loading errors.

Deleting the folder and then Verifying Integrity of Game Files (Step 1) forces Steam to download a fresh, clean version of these core components. Summary Checklist Verify Files: Fixes 80% of cases. Exclusions: Stop your Antivirus from "eating" the DLLs.

Updates: Ensure Windows and C++ Redistributables are current. Clean Boot: Turn off overlays like MSI Afterburner.

By following these steps, you should clear the "Additional DLL" error and get back to the lobby. If the problem persists, a full clean reinstallation is the final nuclear option, but usually, a quick file verification does the trick.

The "additional DLL could not be loaded" error in Call of Duty: Black Ops III is primarily caused by antivirus software quarantining necessary game files.

Suddenly, his monitor flashed a brilliant, blinding white. Leo shielded his eyes. When he looked back, his desktop wallpaper was gone. In its place was a terminal window, running lines of code at a blinding speed.
