WINBIO_E_MAX_ERROR_COUNT_EXCEEDED
WINBIO_E_MAX_ERROR_COUNT_EXCEEDED means the surrounding biometric workflow has crossed an error threshold and was stopped. It is not the first failure in the sequence, so the most useful evidence is the chain of earlier operation statuses and reject details that led to the abort.
Find the repeated precursor error
- Preserve every HRESULT and
WINBIO_REJECT_DETAILvalue for the enrollment or authentication attempt. - Record the unit ID and operation type so device failures are not mixed with bad-capture guidance.
- Stop automatic infinite retry loops; start a fresh transaction only after the underlying repeated condition has been identified.
Enrollment capture, for example, distinguishes accepted samples requiring more data from rejected captures with placement or quality details. Those earlier results explain why a transaction accumulates failures. Treating only the terminal HRESULT loses the diagnostic sequence and can cause an application to restart the same unsuccessful operation indefinitely.
