The Quick Fix: Launch Options Configuration

Step 1: Access Game Properties

Right-click on ARC Raiders in your game library and select Properties.

Step 2: Add Launch Options

Locate the Launch Options field within the Properties menu. This is where you’ll input the command that fixes the multiple instances error.

Step 3: Enter the Command

In the Launch Options field, paste the following command exactly:

-EAC_launcher_delay 5000 -no_multiple_instances

This command works by:

-EAC_launcher_delay 5000 — Adds a 5-second delay to the Easy Anti-Cheat launcher

-no_multiple_instances — Prevents multiple game instances from launching simultaneously

Why This Solution Works

Many players attempt to fix the multiple instances error through other methods such as restarting the game, uninstalling cheat detection software, or modifying system settings. However, this launch option approach directly addresses the root cause by configuring how the anti-cheat system initializes. Once you apply this fix, it will work permanently without requiring any additional restarts or manual intervention.
