Some ECUsuite-based platforms launch a background service (e.g., eCUartDaemon.exe or AlientechUpdateService ). If that service crashed or is stuck in a zombie state, the next attempt to initialize edc17dll exclusive will see a lock file or mutex and abort.

print(f"\n📁 Checking DLL: dll_path\n")

if "LOCKED" in access_status: print("1. Close all ECU tuning software (EDC17Suite, WinOLS, KTAG, PCMFlash, Ediabas).") print("2. Open Task Manager → End tasks of any OBD or flashing tools.") print("3. Restart your PC to release any stale file locks.")

: Open the Command Prompt as an administrator and run sfc /scannow to repair generic Windows system files that may be preventing the initialization of third-party DLLs.

If the issue persists, your Windows system files may be corrupted. Open Command Prompt as Admin.
