Getting "ace-base" error on all Easy Anti-Cheat games (Fortnite, Halo Infinite, etc.)

Hello, I'm encountering a startup error that prevents me from launching the game. Each time I try to start it, I receive a message saying: "Please close the ACE-BASE application before starting the game."

I have no idea what ACE-BASE is or why it's interfering. I checked Task Manager and tried closing background applications, but nothing helped. I've also followed every potential fix I could find on Reddit, YouTube, and other online forums—but the issue still persists.

This has become very frustrating. I just want to play the game I paid for without unnecessary technical barriers. Please provide a proper solution or release a patch that resolves this conflict. It’s unreasonable for a background or unknown application to block access like this.

  • ACE is an anti-cheat used by Delta Force, Infinity Nikke, Wuthering Waves and probably many more games.

    Rootkit anti cheats don't like each other running at the same time and I find it plausible there's a leftover ACE process running somewhere.

    I'd say check services.msc (it's an app on Windows) for any anti cheat services running in the background
