Track installation
- Navigate to the drive where your Steam install is.
- Drill down to the following folder....
- Program Files(x86)\Steam\Steamapps\common\assettocorsa*\content\tracks
- Once you've reached the tracks folder, you should see the tracks that come with the game. If you see those, you're in the right place.
- Minimize this window if necessary and go open the zip file for the track you want to install.
- Copy the folder contained in the zip. Paste it into the tracks folder.
That's it!
Side note: this is the exact same way you install skins, apps, cars, everything. I can write up specific tutorials for those things, but it should be fairly easy to figure out once you got the tracks installation down pat.
Any questions, just ask.
*I recommend putting a shortcut to this folder somewhere easily accessible. I have mine on my desktop. This way you won't have to drill down like that every time you want to install a track.
