OLE_E_WRONGCOMPOBJ
OLE component versions are incompatible
OLE_E_WRONGCOMPOBJ is HRESULT 2147745806 (0x8004000E) from winerror.h. The documented description is “compobj.dll is too old for the ole2.dll initialized” The result belongs to legacy OLE initialization involving compobj.dll and ole2.dll. A reliable diagnosis preserves the raw value and reconstructs the state that made this true: the loaded compound-object component is too old for the initialized OLE runtime.
OLE_E_WRONGCOMPOBJ means that the loaded compound-object component is too old for the initialized OLE runtime.
Where the result appears
- This result can surface in a compound-document containers, embedded or linked objects, OLE activation, advising, caching, conversion, and persistence.
- Map the failure to one concrete operation among IOleObject, IOleLink, IOleCache, IAdviseSink, IPersistStorage, IOleInPlaceObject, monikers, verbs, and client-site callbacks.
- Preserve CLSID, object and client-site identity, storage or moniker, advise cookie, verb, activation state, window generation, and presentation format before releasing or replacing the object that returned this result.
An incident record must distinguish caller, runtime, provider, and backing resource while testing whether the loaded compound-object component is too old for the initialized OLE runtime.
Typical causes and interpretation
The immediate contract boundary is specific: the loaded compound-object component is too old for the initialized OLE runtime. Common cause branches include the following:
- Private legacy DLLs shadow system components.
- An incomplete application install mixes OLE generations.
- Compatibility packaging redirects the wrong binary.
Confirm the cause branch that explains why the loaded compound-object component is too old for the initialized OLE runtime by using call arguments, object state, metadata, device information, or provider traces.
Correct handling and recovery
The primary recovery is to remove private system-component copies and repair the application or operating-system installation as a consistent set. The failure report should capture the relevant state during legacy OLE initialization involving compobj.dll and ole2.dll so it is clear why the loaded compound-object component is too old for the initialized OLE runtime.
When it follows cancellation or replacement, create a new generation before applying the recovery: remove private system-component copies and repair the application or operating-system installation as a consistent set.
Practical scenario
A legacy product directory contains an obsolete compobj.dll that is loaded before the system version; removing the private copy fixes initialization.
Difference from related HRESULTs
STG_E_BADBASEADDRESS concerns an unexpected OLE32 load address; it concerns incompatible OLE component versions.
Developer and administrator guidance
A runbook should preserve the original artifact and logs before the proposed recovery—remove private system-component copies and repair the application or operating-system installation as a consistent set—changes evidence.
