Black Ops 2 Cannot Create Steam-api.dll Guide

If files are corrupted or completely missing, you can force the Steam client to verify and recreate the exact library extensions you need.

The most reliable fix for the permissions conflict is moving the game library out of the protected Program Files directory. By moving the Steam Library to a custom folder (e.g., D:\Games ), the user removes the Windows UAC (User Account Control) bottleneck. Steam then has free rein to create and modify files without requesting elevation. black ops 2 cannot create steam-api.dll
