WINBIO_E_ADAPTER_INTEGRITY_FAILURE
WINBIO_E_ADAPTER_INTEGRITY_FAILURE occurs at the plug-in trust boundary. WBF biometric units are built from sensor, engine, and storage adapter components that the privileged Windows Biometric Service loads into a processing pipeline; a binary that fails integrity validation cannot be treated as a normal operational adapter.
Identify the exact adapter binary
- Map the failing biometric unit to its sensor, engine, and storage adapter registrations.
- Verify that the installed binaries and deployment package match the intended signed build rather than mixing versions from different driver packages.
- Correlate service and code-integrity events before attempting application-level enrollment or capture retries.
An adapter integrity failure is fundamentally different from WINBIO_E_CONFIGURATION_FAILURE. Configuration can fail while loading or connecting otherwise trusted components; integrity failure says the adapter binary itself did not pass the required check. Replacing templates or changing pool selection will not repair that trust failure.
