DLC American Wilds – Free! (Correct installation) vx32 / x64
The method is old, but not everyone, as I see it, still knows about it! (and this is to some extent good).
Installation:
Copy content to game folder with replacement! (not in the Media folder and not in the System32 folder, but where the .EXE games are located)
(In the Steam library \ in the dls list – it will not appear for you, but Steam will think that it is purchased).
If anyone is interested in how it works, google for the words: CreamApi Steam
!!! Please – do not yell about it in all forums !!!
Version x32 / x64 for Spintires: MudRunner (v25.02.21):
– Added support for bit depth (x64) for the game version 25.02.21.
