If Fix #1 didn't work, Steam might have lost track of where the game lives.

The Call of Duty: Ghosts "filesyscheck.cfg" error is a classic example of a poorly communicated file path issue. It is frustrating, but it is not fatal.

The "Error during initialization: Couldn't load fileSysCheck.cfg" in Call of Duty: Ghosts is a common startup issue that typically indicates the game is not being launched from its correct root directory. This error prevents the engine from locating essential configuration files required for initialization. Primary Solutions for fileSysCheck.cfg Error

If you are encountering this error on PC, follow these verified troubleshooting steps to resolve the file path mismatch or corruption: 1. Modify the "Start In" Folder Path

Often, game shortcuts point to a subfolder (like /bin) rather than the main directory where the configuration files reside.

Right-click the Call of Duty: Ghosts shortcut on your desktop and select Properties. Locate the "Start in" field.

If the path ends with \bin, delete the word bin but keep the trailing backslash. Click Apply and then OK before relaunching the game. 2. Verify Game Files (Steam)

If you are playing through Steam, the error may be caused by missing or corrupted data in the main folder where fileSysCheck.cfg should be located.

Open your Steam Library and right-click on Call of Duty: Ghosts. Select Properties > Installed Files.

The filesyscheck.cfg error often arises during the game's startup or when it tries to validate its files. This configuration file is crucial for the game to perform a file system check, ensuring that all game files are present and intact.

This tricks the game into thinking the file check passed. It is a band-aid, not a cure, but it will get you into the game.

Players with RTX 30-series or 40-series cards report the filesyscheck.cfg error more frequently. Why? The 2013 game doesn't recognize modern GPU architecture and falsely flags the graphics driver DLLs as "tampered files."

Solution: Limit your GPU’s PCIe version to 3.0 in BIOS, or use NVIDIA Inspector / AMD Radeon Pro to force Call of Duty: Ghosts to run in DirectX 11 legacy mode.

This sounds counterintuitive, but the game will regenerate a working version if the rest of your install is healthy.

A recent Windows update changed how User Account Control handles .cfg files. If you are on Windows 11 version 24H2 or newer:
