Have you ever received the ''Another instance of the game is already running'' error when trying to launch the game? It may show something similar to the below image:

 

Below, you'll be able to find some potential solutions for resolving this issue!

__________________________________________________________________________________

First, we would recommend to check the Task Manager to make sure that Hell Let Loose is closed. To open Task Manager press Ctrl + Alt + Del, then select Task Manager and look for Hell Let Loose. If it's on the list, right-click and "End task". Then go back to Steam and try to open the game again.

If it is and the problem continues, it could mean that another program is using Easy Anti-Cheat.

(eg. Riot Games launcher is using EAC) Please make sure you don't have any EAC-related software running before you run Hell Let Loose.

It could also be due to running a game server in the background, such as Squad Server or Conan Server, or any other server hosting applications/games.

Please make sure to close those servers before opening the game.

Should this not be the case, we would then also recommend to try completely deleting the "EasyAntiCheat" folder:

To do this:

Right click on "Hell Let Loose" in your Steam library, select "Properties", go to "Installed Files" and then click on "Browse..." and then delete the "EasyAntiCheat" folder.

Then, run Steam as an admin:

  1. Navigate to your Steam install folder (Default: C:\Program Files (x86)\Steam)
  2. Locate the application
  3. Right-click it and go to Properties
  4. Click the Compatibility tab
  5. Check the Run this program as an administrator box

And once you’ve done this, please verify your game files:

To do this:

  1. Right-click the game in your library
  2. Go to 'Properties'
  3. Go to the Installed files tab
  4. Click 'Verify integrity of game files...'
  5. Attempt to run the game to see if the issue is resolved

If nothing above works, you can try updating or uninstalling the GeForce App if you have this installed and then attempt to launch the game again.

If you find that the "Another instance of the game is already running" error persists following this, please do reach out and we can take a closer look into what may be causing this.
