COMADMIN_E_BADREGISTRYLIBID
COM registration, type library, and component installation: exact meaning of COMADMIN_E_BADREGISTRYLIBID
The registered type-library identifier is invalid or inconsistent. COM+ follows component registration to a TypeLib value and cannot use the referenced LIBID.
Windows describes this condition as “The registered TypeLib ID is not valid”.
Evidence to collect before repair
- Record CLSID/IID/LIBID values and 32/64-bit registry view.
- Preserve component, type-library, and proxy/stub paths with hashes; it anchors the failure to the real administration object.
- Evidence should include loader or DllRegisterServer/DllGetClassObject result, captured before a repair changes state.
- Collect COM+ installation ErrorInfo and relevant event records when diagnosing this result; without it the symbolic HRESULT is underdetermined.
Where the result occurs
The COM+ catalog presents a split view of RegDB and Windows class/type-library registration, so the failing stage must be identified before editing either store. In the specific case of this result, record CLSID, TypeLib value, version, LCID, registry view, and whether the referenced type library can be loaded.
Diagnostic sequence
- To isolate this result, verify the exact binary architecture and dependencies.
- load and inspect the matching type library without substituting another version.
- repair registration using the component installer.
- The next diagnostic action is to install rather than import when full interface metadata is required.
- To isolate it, repopulate the catalog and test class activation after repair.
Retry and recovery
Repair the component/type-library registration through the installer and reinstall the component.
Practical administration scenario
A copied registry fragment contains a malformed TypeLib GUID, so COM+ cannot connect the class to its interface metadata.
Difference from nearby COMADMIN results
COMADMIN_E_COMPFILE_BADTLB means the actual type library cannot be loaded; this value focuses on the registered LIBID metadata.
