How to Fix Errors Without Downloading

Do not download this file from third-party websites, as they often contain malware. You can repair it using built-in Windows tools:

1. Run SFC (System File Checker)

This utility scans for corrupted or missing system files and restores them from the local cache.

Press Windows Key + X and select Terminal (Admin) or Command Prompt (Admin).
Type sfc /scannow and press Enter.
Wait for the scan to finish and restart your computer.

2. Run DISM (Deployment Image Servicing and Management)

If SFC fails, DISM can repair the local Windows image using files from Windows Update.

Open Command Prompt (Admin).
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Once completed, run the sfc /scannow command again.

3. Restart Biometric Services

If the error occurs during login or facial recognition setup, restarting the service can reload the DLL.

Press Windows Key + R, type services.msc, and press Enter.
Scroll down to find Windows Biometric Service.
Right-click it and select Restart (or Start if it is not running).

4. Reinstall Biometric Drivers

Corrupted device drivers can trigger errors in the face recognition engine adapter.

Right-click the Start menu and select Device Manager.
Expand the Biometric devices section.
Right-click your facial recognition camera/sensor and select Uninstall device.
Restart your PC; Windows will automatically reinstall the driver.
