I use MO2 and I downloaded the newest version of AAF through the discord, but my game won't boot AAF correctly.

You need LL Fourplay plugin for your game version. Download plugin version v58-20251126: Adds support for Fallout v1.11.169.0 and F4SE 0.7.6. Not Src version, but second. 

Install it as mod and load after AAF. Should work

Yep, LL_fourPlay_1_10_984.dll LL_fourPlay_1_11_137.dll and LLfourPlay_1_11_159.dll

As I understand, this error can be ignored. These plugins are for game versions 1.10.984, 1.11.137 and 1.11.159. Don't delete them, keep everything as it's if your AAF setup is working

Latest AAF already contain plugin for your game version: 

 

 

 

What error do you have exactly?

@deff. New to this, I have the latest download of Fo4 from steam, 1.11.191, which one do I use? I have the same error as well. Downloaded the LLFP-v59 and I'm getting four dll errors the same three as above and another LL_fourPlay_1_11_169.dll.

Might be, that at the moment latest AAF don't support latest Steam FO4 version. I mean, if the latest game version is 1.11.191 (Steam or any other) dll plugin must be the for same version. Looks like that plugin haven't be updated yet - I'm away from Fallout 4 moding at the moment and I'm not sure. The easiest way to avoid some problems is to downgrade your game to 1.10.163 or to very first NG updated game. Downgrade you can with downgrader (search in Nexus) or downloading depots from Steam (search in google about this option, it's not very hard). If you will be on 1.10.163 game version, there will be no problems with mods and AAF setup

 

Image is from here. You need one of these game versions, as I said

 

 

And latest AAF contains plugins for these game versions...that means you should downgrade your game.

Just to be clear - I am on game version 1.11.1911.0 on steam --> and when launching I get  error " LL_fourplay_1_10_984.dll disabled" 

 

This is okay to ignore??

 

Thank you,

Sorry, a bit new to modding. Would you please be willing to tell me and by extension the rest of us how to do that? Where are the .dll extensions and how do you find the one your version is on and what to remove? Thank you.

the dll have the compatible versions in their file names. so, you have to know what game version you are on. then remove the ones with different numbers.

 

they are in \F4SE\Plugins within the mod install location

Thanks. I managed to get it taken care of.
