Tools You'll Need

How to Fix Error Code 0x65BC9CD7

  1. Restart Your PC Completely

  2. Close All Background Applications Before Launching

    Do not use third-party macro, automation, or input-injection software while playing Warzone. Even if not intended for cheating, these can trigger a permanent ban.

  3. Disable or Temporarily Pause Your Antivirus

    Only disable your antivirus temporarily for testing. Re-enable it immediately after confirming the fix and add proper exclusions instead of leaving it off.

  4. Disconnect Any VPN or Proxy

  5. Update Your GPU and System Drivers

  6. Scan and Repair Game Files

  7. Reinstall the RICOCHET Anti-Cheat Driver

    Do not manually modify system driver files unless you are comfortable with Windows system administration. Create a System Restore point first by searching 'Create a restore point' in the Windows Start menu.

  8. Check for a Temporary Account Flag or Ban

    Creating a new account to evade a ban is a violation of Activision's terms of service and can result in permanent hardware bans affecting all accounts on your device.

When to Call a Professional

If you have completed every step above and the error persists despite having no cheating software, no VPN, clean drivers, and a fresh game installation, contact Activision Support directly at support.activision.com. Provide them with your Activision ID, platform, and a detailed description of the steps you have already taken. If your account has been suspended and you believe it is an error, the only path forward is an official Activision ban appeal — no third-party service or technician can overturn an anti-cheat decision on your behalf.

Frequently Asked Questions

Does error 0x65BC9CD7 mean I am permanently banned from Warzone?
Not necessarily. This error is triggered by the RICOCHET anti-cheat system and can result from software conflicts, corrupted files, or driver issues — not just cheating. Follow the troubleshooting steps to rule out technical causes first. If your account has been actioned, log in to support.activision.com to check your account status and file an appeal if needed.
Can using a VPN cause Warzone error 0x65BC9CD7?
Yes. VPNs and proxy tools can interfere with the RICOCHET anti-cheat's connection and authentication process, triggering this error. Disconnect your VPN completely before launching Warzone. If you need a VPN for other purposes, make sure it is fully disabled — not just paused — while playing.
Will verifying game files fix error 0x65BC9CD7?
It can. Corrupted game files or a damaged anti-cheat driver installation are common causes of this error. Use the Scan and Repair option in Battle.net or the Verify Integrity of Game Files option in Steam. If corruption is detected and repaired, the error should stop appearing.
Does Discord or OBS cause Warzone error 0x65BC9CD7?
Overlay and capture software like Discord's in-game overlay or OBS Studio can sometimes conflict with RICOCHET. Try disabling Discord's overlay (Discord Settings > Game Overlay > toggle off) and closing OBS before launching. If the error goes away, you can try re-enabling them one at a time to identify which one is the conflict.
How do I appeal a Warzone ban if I got error 0x65BC9CD7 unfairly?
Go to support.activision.com, log in with your Activision account, and navigate to the ban appeal section. Clearly explain that you received error 0x65BC9CD7, that you do not use cheating software, and list any legitimate software that may have caused a conflict. Activision reviews appeals on a case-by-case basis. Be patient — responses can take several business days.
