The "Hot Fix" (3 Steps)

The Fix: How to Kill the v1163 Error for Good

You do not need to uninstall your mods. You just need to outsmart the checksum. Here is the hotfix the sim racing forums are buzzing about:

Method 1: The Steam Reset (For Vanilla Servers Only)

• Go to Steam > Library > Right-click Assetto Corsa > Properties > Installed Files > Verify integrity of game files.
• This will delete your mods and revert you to true v1.16.3. You can now join vanilla servers, but you will lose all your mods. (Not recommended for most users).

Method 2: The Content Manager Workaround (The Real Fix)

• Open Content Manager.
• Go to Settings > Content Manager > Patch.
• Ensure you are on the recommended version of Custom Shaders Patch (currently 0.2.3 or later), not the "bleeding edge."
• Go to Settings > Assetto Corsa > System.
• Toggle "Disable checksums" (If available in your CSP version). Warning: This allows you to join servers, but may cause online mismatches.

Method 3: The Nuclear Option (Force v1163 Signature)

• Download the official "Steam v1.16.3 vanilla data.acd" file from a trusted repository (Back up your current one first).
• Replace the file in assettocorsa/content/car/ (for every car the server uses).
• Pro Tip: Use the "Update Cars" button in Content Manager’s "Tools" section to mass-restore car data to v1163 without deleting your skins.

Step 4: Restart

• Once the download finishes, close Content Manager completely.
• Re-open it. The message should be gone.

Step 1: Verify Your Current Version

1. Launch Assetto Corsa: Start the game to see if there's an option to check the version in the game's main menu or in the settings.
2. Check Game Files: If the game doesn't display the version directly, you might need to check through your game library on the platform you're using (Steam, for example).
