Since July 2026, some PC players get an Easy Anti-Cheat “launch error” in Dead by Daylight that names an outdated driver or program. Behaviour says it is linked to its anti-cheat security update and that you must update the flagged software. So which program was it on your PC, and did updating it get you back into the Fog?

What Behaviour says (read on November 11, 2026):
- The software to update can be RGB or motherboard utilities, CPU/GPU overclocking or tuning tools, certain BIOS utilities, hardware monitoring tools, utilities using direct port access, manufacturer updaters (Dell, Asus, Lenovo, etc.) or other anti-cheat, anti-hack or antivirus software.
- Search for the driver name in the error message and update that program from its maker’s site. If another launch error appears, another incompatible program is probably present: update that one too.
- It is not a Secure Boot requirement, minimum specs do not change, and Linux/Steam Deck players have nothing to do.
- Separately, “Game Security Violation Detected” is often caused by RGB lighting software, which must be disabled to play.
- Behaviour’s “Game Crashing” page (August 28, 2026) also says it is aware of frequent crashes and working on a fix.
Questions for players:
- Which driver or program did the launch error name on your PC (RGB suite, fan control, monitoring tool, overclocking tool, OEM updater, another anti-cheat)?
- Was updating it enough, or did you have to uninstall it?
- Did you get a second launch error naming another program after the first fix?
- Laptop owners: was it a Dell, Asus or Lenovo updater or control app?
- Anyone with “Game Security Violation Detected”: which RGB software was it, and can you keep your lighting while playing?
- Since patch 10.2.2 (October 20, 2026), are random crashes during loading or in a match less frequent for you?
Please share the exact error text (hide any personal info), your Windows version, CPU/GPU, the program that was flagged and what fixed it. Don’t post account details, cheats or links to unofficial downloads.
