Fallout 4 has a thriving modding community that releases new mods for that game. These mods alter the game in various ways.

For example, when downloading mods that enhance visuals or add new features to Fallout 4, in some cases, the mods don’t work or show up in the game.

Why are my Fallout 4 mods not working?

Fallout 4 mods won’t work if you haven’t configured certain INI files for the game as required.

The Windows firewall or antivirus utility might be blocking Fallout 4 or its mods manager. Or the mods manager for Fallout 4 might not have admin privileges.

Faulty (corrupted) or outdated mods can also stop other mods from working.

General issues with the game will arise when there are faulty mods. For example, Fallout 4 might crash with regularity or, in the worst case, not start at all because of broken mods.
