In the vast majority of cases involving Error 4, the antagonist is not the software itself, but the user’s operating system security. Windows Defender and third-party antivirus software are programmed to detect "suspicious behavior." The method TeknoParrot uses to intercept game functions—DLL injection—is a technique frequently used by malware to steal data or modify system processes. Consequently, Windows Defender often flags the necessary DLLs as a threat (specifically "Trojan:Win32/Wacatac" or similar generic detections) and quarantines or deletes them immediately upon extraction or execution.
