After these steps are done, launch the tool and check if mods are detected for Fallout 4.

Configure The .ini Format Files For The Fallout 4 Mods

Files of the .ini format can be misconfigured as you run the game and install mods in it. You may have to manually change the configurations again so that you can make the downloaded mods appear or download them, in the first place, through the Nexus Mod Manager. 

  1. Open a Windows File Explorer (Windows key + E) window and go to the following directory –

This PC > Documents > MyGames > Fallout4

Fallout 4 folder in the My Games directory
  1. Here, you should be able to see a Configuration settings file named “Fallout4Custom.ini”. If you cannot, make a new Notepad++ file and give it the fore-mentioned, highlighted name.
  2. Open this file and include the following lines – 




  1. Go back to the File Explorer window and open the Fallout4prefs.ini notepad file.
  2. Scroll down to the bottom and enter this line –
  1. Save both the notepad files and launch the game.

Allow Fallout 4 Through The Windows Defender Firewall

  1. Open the Control Panel window and click on the Windows Defender Firewall option. If your view mode is set to ‘category’, you will have to go to the System and Security > Windows Firewall.
  2. From the left menu panel, choose the ‘Allow an App or Feature Through Windows Defender Firewall’.
  3.  Click on the Change Settings button at the upper-right part of the page.
  4. Scroll down to the entries of the Nexus Mod Manager and the Fallout 4 game and check the Public and Private checkboxes, that is to their right.

  1. Save these changes and reboot your system to apply these changes.

Both the Fallout 4 game and Nexus Mod manager will be exempted from the Windows Firewall. You will, most likely, not be able to face the Fallout 4 mods not working issue again, on your computer. 

Exempt Fallout 4 From Windows Security Checks

Sometimes the antivirus can also be responsible for quarantining files related to the game and the mod manager. This is because of the scans that detect them as possible threats to the computer.

The only option to get rid of the Fallout 4 mods not working issue on the computer, is to add these files to the exclusion list so that they cannot be detected in the scans.

Each antivirus has a unique interface and thereby, has different methods to add an application or a folder to the list of files excluded from the scan. 

Get Rid Of Corrupt Mods

  1.  Launch NMM with the help of the Nexus Mod Manager icon on your desktop or the installation location.

  1. Click on the Fallout 4 game option and you will see a list of all the mods installed on your computer. 
  2. Now, look for the mods that you cannot see in the game. You should be able to see them listed.
  3. From here, you have to choose between deleting them permanently and disabling them and enabling them again.
    1. Right-click on the mod and choose the Deactivate option. To re-activate it, click on the Activate option in the context menu. 
    2. Open the context menu and choose the Uninstall or Delete option. Here, you have to choose if you want to delete the mod from the computer or uninstall the mod from the game.

You can also try the ‘Reinstall mod’ option. This will uninstall and reinstall the mod from your computer. You will not lose the mod, unless the process is interrupted.

Update The Nexus Mod Manager On Your System

It is important that you have the latest version of the Nexus Mod Manager on your computer. Only then, you will be able to connect with the ever-updating game and make modifications to the game files.

The NMM has an auto-update feature that can be toggled on or off. If you do not want to do it this way, you can always visit the Nexus Github webpage and install the source of the latest version of the game modder.

Check If Fallout 4 Has Updates

There are chances that the game itself has updates waiting to be downloaded and installed. If there are updates, the game may not run. And when the updates are installed, the mods may or may not be compatible with the game.

The only option here is to wait for new, compatible mods to be released. If you are a modder, you can try altering the .esp and .ini files to make the mods fit into the new version of the game.

If you download your Fallout 4 mods from a third-party website, the site may contain details about which version of the game can host the mod. For updating the game, you can use the platform through which you purchased Fallout 4 in.

Install Windows Updates, If Available

  1. Open the Windows Settings (Windows + I) window. Here, click on the Updates & Security settings tile.
  2. You will be taken to the Windows Update page. Now, click on the Check for updates button, if there are pending system or driver updates
  3. Then, press the Download and Install button, once you make sure that you have a proper internet connection.

Turn On Multi HD Install

For the Nexus Mod Manager to install the mods correctly onto your Fallout 4 game, both the NMM tool and the game should be installed on the same partition of your hard drive.

However, you can still make it work when the game and the mods/mod manager are installed in separate locations. This is possible when you enable ‘Multi HD install’ element on the NMM, during the installation process of mods.

When the mods are being installed into the game, you will have to enable Multi HD install for the mods to work. Your only other alternative solution, in this case, is that both the mods and the game have to be in the same drive partition.

Arrange The Loading Order Of The Mods

The final solution is not known to work as expected but there are chances that this is the breakthrough you’re looking for. Changing the order of the mods that load in the Fallout 4 game, through the Nexus Mod Manager, might help you fix Fallout 4 mods not working error on your computer. 

You just have to open the Nexus mod manager, go into the Plugins tab and drag the .esp files up or down to arrange them in any order. Try prioritizing the larger files or the smaller ones and not in random order. 

These are the solutions we managed to use to help install or detect Fallout 4 mods through the Nexus Mod Manager
