ERROR_EVT_INVALID_EVENT_DATA
The published event payload is incompatible with its template
An event template defines each data item, its order, input type, optional output type and any array or structure relationship. The provider must write fields in that exact order. A changed structure, wrong field count, incorrect type or inconsistent array length can make the runtime payload impossible to interpret using the registered template.
Debug the producer and its installed manifest together. Verify that the generated event descriptor and write call come from the same manifest build as the registered resource. This code is different from a message-formatting failure: the raw event data itself does not conform, so replacing a localized message DLL alone will not correct it. Capture the event ID, version and provider build to detect stale deployment.
What to inspect
- Compare the write-site field order with the manifest template.
- Check event ID and version against the installed provider metadata.
- Rebuild and deploy generated headers, manifest and resources together.
