Run F4SE through the Fallout 4 Launcher (Might not work after every update directly because F4SE needs to update after Fallout4)

In this guide I'm going to give you the steps to run Fallout 4 Script Extender through the Fallout 4 launcher. (Beware that by default Windows doesn't show File Extensions so just leave the .exe out of the name if you don't see the .exe in it)

How to run f4se through the fallout 4 launcher.

IMPORTANT NOTE: EVERY TIME FALLOUT 4 UPDATES IT WILL BREAK AND YOU HAVE TO REDO STEPS 1, 2 and 3

To get the newest version of f4se go to http://f4se.silverlock.org/

1) Go to your Fallout 4 folder, which most likely is -"C:\Program Files(x86)\Steam\Steamapps\Common\Fallout4\"
2) Rename the Fallout4.exe to F4.exe
3) Rename f4se_loader.exe to Fallout4.exe
4) Go to \data\f4se\ - if the f4se folder doesn't exist, create it.
5) Make a file called f4se.ini and write this in it

[Loader]
RuntimeName=F4.exe

6) Save file
7) Start Fallout 4 via steam and hit Play

Issues and Fixes

ATTENTION BEFORE YOU START MAKE SURE YOU HAVE "SHOW FILE EXTENSIONS ON IN YOUR FILE EXPLORER" if you do not know how to, Click View in the top left of file explorer and the option should be over to the right named "File name extension" without this on your file won't change its file extension when you change the name of the file.

This method can mess up Nvidia SLI to prevent this add F4.exe to the Fallout 4 profile via Nvidia Inspector. This will ensure SLI and any game tweaks via drivers work.

For the people with infinite launcher. Are you sure you renamed the Fallout4.exe and not Fallout4Launcher.exe

For the people that say making a shortcut is easier.
While this may be true this doesn't launch the launcher and instead launches the game directly which makes you unable to tweak the game settings before launching the game

Thank you author and thank you, Darklord!
Finally it works.

Thanks that works.
No ini file was necessary for me

erm, ok .... NERD XD

[Crow Fross]

Thanks, Darklord, but the .ini file is still necessary.

vv thank you Darklord, that worked perfectly

Yeah, that doesn't work because the steam start-button opens the launcher, and you need to bypass the launcher for SE to work

What you actually need to do is:
1. Rename the launcher "Fallout4Launcher.exe" to something else. I use "Fallout4LauncherBackup.exe"

2. Rename the SE-loader "f4se_loader.exe" to "Fallout4Launcher.exe"

And that's all you need to do.
Now when you click the start-button it starts the renamed SE-loader, completely bypassing the launcher.

No ini-file necessary. If you created it, delete it again, it won't work.

If you need the launcher (e.g. to change graphics settings) you can manually start your "Fallout4LauncherBackup.exe" from the install-folder.

I think the launcher passes launch arguments onto the game when starting it that F4SE doesn't recognize

[Kuldiin]

Followed this and get "Couldn't read arguments' when launching.

Launching F4se direct works fine, just not via Steam.
