Two ways:
- Rerun Get Started Wizard:
Settings -> General -> Start Wizard - Directly by enabling ACC from the dropdown in:
Settings -> Sim Connection -> Racing Simulators
You will need to enable Broadcasting as well. You need to edit your broadcasting.json file in the ACC config folder. At minimum, you must set the updListenerPort value. The broadcasting.json file is located in: Documents\Assetto Corsa Competizione\Config\.
You can use these settings that mirror the test client’s default values:
{
"updListenerPort": 9000,
"connectionPassword": "asd",
"commandPassword": ""
}
Make sure to restart both ACC and DRE after these changes.
