CO_E_TRACKER_CONFIG
COM object tracker configuration is invalid
CO_E_TRACKER_CONFIG is HRESULT 2147500080 (0x80004030) from winerror.h. The documented description is “The provided tracker configuration is invalid.” The value must be interpreted at runtime configuration for object tracking, lifetime monitoring, or related COM infrastructure.
One or more tracker settings form an unsupported or internally inconsistent configuration. Keep the symbolic name beside the raw hexadecimal value so later analysis does not collapse the result into an unrelated COM family.
Where the result appears
- This result may surface in runtime configuration for object tracking, lifetime monitoring, or related COM infrastructure.
Determine the object and lifecycle phase that owned this result; a UI symptom cannot establish whether the origin was the caller, proxy, runtime, server, or metadata producer.
Typical causes and interpretation
Common cause categories are: unknown fields were introduced; limits conflict; a deployment wrote values for another build; numeric ranges are invalid. Evaluate these branches independently and require evidence from the owning API before promoting one branch to the root cause.
Key distinction: one or more tracker settings form an unsupported or internally inconsistent configuration.
Correct handling and recovery
The appropriate recovery is to validate configuration against the installed schema, restore supported defaults, and roll out tracker changes atomically with the matching component. The owner of retry must define idempotency, refreshed state, maximum attempts, backoff, and cancellation responsibility.
After this result, apply the API-specific validity rules to outputs and release only resources whose ownership transferred during this attempt.
Practical scenario
A deployment copies tracker settings from a newer OS image; reverting the unsupported field allows the service to initialize.
A regression test should force the relevant precondition, assert native outputs, fix only that condition, and confirm the expected neighboring result.
Difference from related HRESULTs
CO_E_THREADPOOL_CONFIG and CO_E_SXS_CONFIG identify invalid configuration in different COM subsystems.
