Fallout 4 Script Extender (F4SE) Install Guide

What is the Fallout 4 Script Extender?

Fallout 4 Script Extender, also known as F4SE or FOSE is a community made modder’s resource that expands the scripting capabilities of Fallout 4. It’s required for quite a few mods that you might want to download.

I currently have two mods installed that require me to use F4SE. The first is “Place Everywhere“, which allow me to build settlement objects anywhere I want, such as inside of walls and terrain.

The second mod is “Achievements“, which allows me to keep earning achievements, even while using mods. Bethesda made the decision to disable achievements if you choose to mod your game. But I guess we all should have expected that a mod would be made to combat that.

How to install Fallout 4 Script Extender

Installing F4SE is a simple task, but it can seem a bit confusing to those of you who are new to modding. I’ll try to break it down to a few step process.

1. To start, head to the F4SE website.
2. At the top of the page, you’ll see a link which says “7z Archive”, next to Fallout 4 Runtime. Click this, and it will download a .7z file, which you’ll need a program like WinRAR or 7zip to open.
3. All you need to do is highlight all of the files inside, and drop them into your Fallout 4 Folder. This is usually at C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 but it may be different for you.
4. Make sure you transfer them all over. You want to ensure that f4se_loader.exe is in the same folder as Fallout4.exe
5. That’s it. You’ll just need to remember to update the Fallout 4 Script Extender whenever Bethesda updates Fallout 4. To actually use F4SE, you will need to run f4se_loader.exe instead of Fallout4.exe to run the game. Mods that require F4SE won’t work unless you run the game through f4se_loader.exe
