🏎️ Manual Installation Guide

Installing mods in Assetto Corsa manually follows a strict directory structure. While Content Manager is recommended, knowing the manual path is essential for troubleshooting.

📁 Finding the Game Root

Your game directory is usually found at: C:\Program Files (x86)\Steam\steamapps\common\assettocorsa

📦 Installation by Category

Ensure you follow the table below to place files in the correct location:

Mod Type Destination Folder Description
Cars content/cars Each car must be in its own folder.
Tracks content/tracks Contains circuit layouts and map data.
Python Apps apps/python For in-game overlays and utilities.
Showrooms content/showroom Custom backgrounds for the car viewer.
Fonts content/fonts Required for some custom HUDs.

[!IMPORTANT] Subfolder Trap: When extracting a mod, ensure the folder you drop into content/cars contains data.acd (or a data folder) immediately. If there is another subfolder with the same name, the mod will not load.


🛠️ Troubleshooting

  • Grey Screen: Usually means the car is missing a required sound fix or the folder name contains illegal characters (keep it lowercase, no spaces).
  • Missing Track: Ensure the track folder has a models.ini or .kn5 files directly inside.
