typically occurs when Windows Defender or other antivirus software incorrectly flags and quarantines critical game files like SLF64.dll as threats. It can also stem from missing core system components like DirectX or Visual C++ redistributables. Core Fix: Antivirus Interference
This is the most common solution for the "additional DLL" error. BO3 was built using Visual Studio 2015. Modern Windows installations often prioritize newer versions (2017, 2019, 2022), which are usually backward compatible, but BO3 is stubborn. It specifically craves the 2015 libraries. typically occurs when Windows Defender or other antivirus

Windows Defender often identifies BO3's dynamic link libraries as "severe threats" (e.g., Trojan:AndroidOS/ZkarletFlash) and removes them. to ensure the game has the necessary permissions
To understand the error, one must first appreciate the function of a DLL. These files are not arbitrary fragments; they are pre‑written bundles of code that multiple programs can use simultaneously. For Black Ops III , critical DLLs manage DirectX rendering (e.g., d3d11.dll or d3d12.dll ), audio processing ( XAudio2_7.dll ), input handling, and even DRM verification. When the game’s launcher attempts to load an “additional” DLL — likely one installed by a patch, a mod, or a redistributable package — it expects that file to reside in a specific directory (either the game folder or a system folder like System32 ) and to be digitally intact. The error “could not be loaded” means one of three things: the DLL is missing, it is corrupted, or it is blocked from execution by permissions or software interference.
If verification completes successfully but the error persists, the problem is almost certainly a third-party mod. BO3 loads additional DLLs from mods stored in your workshop folder.
