# Fix Modern Warfare 2019 Aimbot and Anti-Virus Issues

> Resolve the N10003 error and non-working aimbot or ESP in Modern Warfare 2019 by completing PC Setup and correcting your Exploit Protection settings.

If you're running a product in Modern Warfare 2019 and encountering errors or features that aren't working, the cause is almost always related to anti-virus or Windows security settings. All Modern Warfare 2019 tools are download-and-play once your system is properly configured.

## N10003 Anti-Virus Error

This error is caused by anti-virus or Windows security settings interfering with the loader.

**Fix:** Follow the [Anti-Virus Setup](/pc-setup/anti-virus-setup) guide and make sure every step has been completed — including disabling Core Isolation, Exploit Protection, and Firewall settings.

## Aimbot and ESP Not Working

If aimbot and ESP features load but don't function correctly in-game, your Exploit Protection settings are not configured correctly.

**Fix:** Open Windows Security → **App & Browser Control** → **Exploit Protection Settings** and configure the settings to match the required configuration. Make sure all exploit protection mitigations are disabled as covered in the [Anti-Virus Setup](/pc-setup/anti-virus-setup) guide.

<Warning>
  Partial anti-virus disabling is a common cause of features silently not working. Windows Defender's behavioral monitoring and exploit protection can interfere with cheat features even when real-time scanning appears to be off. Disable every layer as described in the setup guide.
