Disabling Fallout Auto update

[endomiel]

I've had it happen twice now over the years that Steam messes up my nice mod-install by auto-updating the game. Is there a way to prevent this?

 

Thanks in advance!

It's been a while!

for steam I think you will need to go to the library, right click on game go to properties/updates find background downloads and set it to never. Not 100% sure this is right but it's close.

Find the steam manifest file for fallout 4. It should be called "appmanifest_377160.acf" in the steamapps folder. (If not sure open the file in a text editor and at the top it will say  "name"     "Fallout 4" ).  Anyway once you've determined that you have the correct ".acf" file, in file explorer, right click on the file and mark as 'Read Only'. Job done. Steam uses that file to know how far it's got through an update for the game. If it can't write to it, it can't do the update.

 

Pre CC Fallout 4 user ?

 

ps

 

Technique same for any game as I'm also a Steam SE April 2018 user ?

Close enough.

 

Steam Library, go to Fallout 4, right click -> Properties -> Updates. On Automatic Updates select "Only update this game when I launch it" and set Background downloads to "Never allow background downloads". That way the game will only start updating when you launch it through Steam, while for normal playing one should use the script extender launcher (f4se_loader.exe). Even then I'd keep a copy of the executable (fallout4.exe or however is called) on a safe place in case an update is done by accident (keeping it on a zip file is enough to have a copy, in case of an unwanted update just replace the executable with the zipped one). That's how I do it with Skyrim SE and I think the same applies to FO4.

Thank you both!
