Introduction

The newest major Windows 11 update “24H2” is slowly rolling out. Once installing the update, Just Cause 3 Multiplayer will always crash with a WindowsCodecsext dll error

But don’t worry! The mod’s creators may have abandoned it, but the community hasn’t! Within less than a day, my amazing friend Jason098 made a simple yet effective fix!

All you need to do is follow the simple steps below, and the mod will continue to work just like before! So follow along:

Step 1

Visit the folder linked below on the Just Cause archive and download both files:
https://drive.google.com/drive/u/0/folders/1iyBKPpR94EsfR1XSWR2X57-BCGmzCaIV

Step 2

Open Steam, go to your library and find Just Cause 3 Multiplayer in your list of games

Step 3

Right click it and click on ” properties”

Step 4

In the new window that pops up click “Installed Files” on the left, then “Browse…” in the top right

Step 5

You are now in the game’s install folder. Now simply paste the two files you downloaded earlier in here

And done!

That’s it, it now works just like before! Have fun playing!

for anybody wondering why it does not work you need to put the vfs code into the steam stuff in library for it to work

I don't think this method works anymore, it keeps displaying the same error message even after I tried all the steps. Any ideas?
