XIGNCODE3 is the anti-cheat system by Wellbia used to detect hacks, bots, and memory tampering in online games like Knight Online. Use this tag for questions about XIGNCODE launch errors, crashes, and error codes (like e0190304 or 0xE019xxxx), the xhunter1 driver/service, false positives from antivirus, read-only folder issues, or the anti-cheat blocking your client from reaching the login screen. Also fits questions about clean reinstalls, Windows 11 compatibility, and driver conflicts tied to XIGNCODE. Combine this tag with a game-specific tag (like #knight-online) and your OS so answers match your exact setup and game version.
