Error - The biometric unit could not be configured - Windows Biometric Framework

Lukuta 1

I have been experimenting with the Windows Biometric Framework in C++. I am trying to use the Private pool to setup a database and enroll fingerprint units and identify them. When I run the setup sample code for client application on the below microsoft links, I am getting a success message but I can't see the private database in WinBioDatabse folder. However, I can see that a database is registered in the registry under the path below

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WbioSrvc\Databases\

Further when I run the enrollment sample code, I am getting the an error error :The biometric unit could not be configured. I am using an inbuilt fingerprint sensor on an HP laptop running Windows 10 OS.
Kindly help with what could be causing this and how to overcome it

If the value Filepath is empty? If so I suggest you could change the value Filepath from empty to correct name. I suggest you could refer to the thread: https://stackoverflow.com/questions/44253772/error-the-biometric-unit-could-not-be-configured-after-uninstall-app-using-wi

The value path is ok. I also had tried the suggested solution from stackoverflow.com and didn't help.
I have also noticed that the private pool in registry has Format with zeros under data column.

Hi. Thank you for your question and reaching out.

If any fingerprints remain in the Sign in option, check and remove them.

Uninstall the device by going to Device Manager. To uninstall a device from this system, select the sub-option.

Restart the computer

Return to the sign-in choices and enroll the finger once more. If it doesn't work, reboot and try the full process again.

Although I believe that this driver is partially defective, I am unable to use another one at the moment. By including my hardware id in the.inf file, I attempted to trick a newer driver into accepting this device, but it was unsuccessful.
