The DAEMON_ERROR in Cyberpunk 2077 is triggered by a mod conflict that prevents the game from launching correctly. This typically happens after a game update, when an installed mod becomes incompatible with the current version of the game or with another mod in your load order. The good news is that this error is almost always fixable without reinstalling the entire game.

How to Fix Error Code DAEMON_ERROR

  1. Back Up Your Save Files

    Always back up save files before modifying game files. Some mod removals or file verifications can corrupt existing saves if done carelessly.

  2. Disable All Mods Immediately

  3. Verify and Repair Game Files

  4. Update or Remove Cyber Engine Tweaks (CET) and RED4ext

    Do not mix version numbers. Installing a CET or RED4ext version that does not match your game patch version will cause the DAEMON_ERROR to persist.

  5. Re-enable Mods One at a Time

  6. Check the Cyberpunk 2077 Log Files for Specific Conflicts

  7. Update Your GPU Drivers

  8. Disable Overlays and Third-Party Software

When to Call a Professional

This error is almost entirely self-serviceable by following the steps above. However, if the DAEMON_ERROR persists after completely removing all mods, verifying game files, and updating drivers, consider posting on the Cyberpunk 2077 subreddit (r/cyberpunkgame) or the official CD Projekt Red support portal at support.cdprojektred.com. Community moderators and CD Projekt Red support staff can analyze your specific log files and provide targeted assistance. If a recent Windows update or hardware driver change appears to be the root cause, consulting a PC technician may be warranted.

Frequently Asked Questions

What causes DAEMON_ERROR in Cyberpunk 2077?
DAEMON_ERROR is almost always caused by a mod conflict on game launch. It most commonly occurs after CD Projekt Red releases a game update that breaks compatibility with installed mods — especially core modding frameworks like Cyber Engine Tweaks (CET) or RED4ext. Outdated or conflicting .archive mod files are the leading cause.
Can I fix DAEMON_ERROR without losing my save files?
Yes. DAEMON_ERROR is a launch-time mod conflict and does not affect your save files directly. As long as you back up your saves before making changes (located at C:\Users\[YourUsername]\Saved Games\CD Projekt Red\Cyberpunk 2077), you can safely remove mods, verify game files, and re-add mods without any risk to your progress.
Does DAEMON_ERROR mean I need to reinstall Cyberpunk 2077?
No. A full reinstall is rarely needed to fix DAEMON_ERROR. In the vast majority of cases, disabling mods and verifying game files through Steam, GOG, or Epic resolves the issue. Only consider reinstalling if multiple verification attempts fail and CD Projekt Red support confirms it is necessary.
Which mods most commonly cause DAEMON_ERROR?
The most frequent culprits are outdated versions of Cyber Engine Tweaks (CET), RED4ext, redscript, and ArchiveXL. These are core modding frameworks that many other mods depend on. After any Cyberpunk 2077 patch, check the Nexus Mods pages for these four frameworks first and update them before re-enabling any content mods.
How do I stop DAEMON_ERROR from happening after future game updates?
The best practice is to pause automatic game updates on Steam (right-click game > Properties > Updates > set to 'Only update this game when I launch it') so you can wait for mod authors to update their files before the new version runs. Follow mod authors on Nexus Mods to get notifications when they push compatibility updates after a game patch.
