The Fallout 4 Script Extender, also recognized as “FOSE” or “F4SE” is a community-developed modder’s resource that increases the Scripting inclinations of the game. Though, quite recently, a lot of news has been coming in of the F4SE not running. The software crashes while trying to start or show a black screen for an extended period before hitting.
What Causes the Fallout 4 Script Extenderto Stop Working?
We reviewed the matter after receiving information about the error and came up with a set of explications that you can perform to get rid of this problem. Also, we looked into the causes of the problem that triggered the issue, and some of the most common ones are listed below.

How to Resolve Fallout 4 Script Extender/F4SE Not Working Problems
Updating the F4SE application
Developers essentially don’t sustain third-party modding facilities for their games and therefore try to check those in every game update. It is reasonable that the Creation Club updated and is now blocking you from using the F4SE application. Consequently, it is suggested to update the F4SE software. For that:
- Download the Latest Version of F4SE.
- Extricate the “f4se_1_10_120.dll(the numbers can alter depending on versions)”, ”f4se_loader.exe”, and the “f4se_steam_loader.dll” to the fallout installation folder.
- The default file path is usually:
- C:\Program Files (x86)\Steam\SteamApps\common\Fallout 4\
- Start the game by executing the “f4se_loader.exe” that you just copied inside the folder.
Note: Override any Files when asked while copying.
Disabling Conflicting Mods
Another possibility is that the mods you have installed might conflict with the F4SE complication due to them being outdated or malfunctioning. Also, if the mods and the F4SE software coincide, it can cause problems with the application. Therefore in this move, we are going to disable all conflicting mods.
- Open the Nexus Mod Manager.
- Right-click on a Mod that is not recommended by NMM and is fitted through the F4SE.
- Disable the mods one by one and attempt to start the game after disabling each one.
- If the game launches once you disabled a particular mod, the conflict was caused due to that mod.
- Try to upgrade the Mod and monitor to see if the problem persists.
- If the Mod still causes issues, disable it until the Mod developers fix the problem.
The plugins utilized by the software might be damaged or outdated and thus causing the issue. The application automatically replaces these if they are deleted. Therefore in this stage, we will be removing these plugins, which will later be automatically overridden.
- Navigate to the Fallout 4 Installation folder it is usually found in C:\Program Files (x86)\Steam\SteamApps\common\Fallout 4\
- Open the “Data>F4SE>Plugins” Folder.
- Delete everything inside the Plugins folder.
- Presently download the Fallout 4 Script Extender then install it.
- Make sure also to reinstall all the fallout four script extender Mods.
- Open the game and monitor to see if the problem persists.
Run Compatibility Troubleshooter
Sometimes, the application might be facing issues with your operating system. Therefore, it is always a great idea to run the compatibility troubleshooter for the software and let it choose the best settings for you. For that:
- Navigate to the game installation folder.
- Now, Right-Click on the “f4se_loader.exe” and press on the settings.
- Press on the “Compatibility” tab.
- Choose the “Run Compatibility Troubleshooter” button.
- Windows will now automatically decide the best settings for your PC.
- Examine those settings and apply if the problem is solved.
Verifying Integrity of Files
In some cases, the game might be missing essential files necessary for the game to run correctly. Therefore, in this step, we are going to be testing the game files. For that:
- Start the Steam software and log in to your account.
- Head to the Library then Right–Click on Fallout 4.
- Select Properties.
- Click on the “Local Files” tab.
- Select the “Verify the integrity of game cache” option.
- Steam will now take some time to verify the game files; once it is finished, try to run the game and check if the problem persists.
Granting access in Firewall
The windows firewall might be blocking the game from making connections with the game servers. At this level, we are going to be allowing the software through the Windows Firewall.
- Click on the start menu and select the Settings Icon.
- From the Settings, choose the “Updates & Security” option.
- Press on the “Windows Security” option from the left pane.
- Inside the Windows Security option, select “Firewall and Network Protection.”
- Choose the “Allow an app through firewall” option.
- Click on “Change Settings” and grant all the Fallout4 related applications access through both “Private” and “Public” networks.
- Click on “OK,” run the game, and check to see if the problem persists.
Running as an Administrator
There are several instances where because of stern protocols because of UAC, F4SE is unable to compile correctly. Since F4SE makes use of scripts, they need elevated permissions to operate. If you are not operating the program with administrator privileges, you might face an issue.
- Please travel to the primary executable of F4SE, right-click on it and choose Run as administrator. You can also set the application to always run with administrator access using the compatibility tab.
- Once with administrator access, examine if the problem is resolved for good.
