COMADMIN_E_COMPFILE_LOADDLLFAIL
COM+ component-file analysis: exact meaning of COMADMIN_E_COMPFILE_LOADDLLFAIL
COM+ found the component file but could not load it for analysis. The component-file inspection stage invokes the Windows loader to discover classes or registration information.
Windows describes this condition as “The DLL could not be loaded”.
Where the result occurs
This HRESULT is raised while COM+ inspects a proposed component file for classes, type information, and class factories before it can create usable catalog components. In the specific case of this result, collect loader status, PE architecture, dependencies, activation context, file integrity, and security blocking information.
Evidence to collect before repair
- Evidence should include exact file path, hash, PE architecture, and signature, captured before a repair changes state.
- Collect loader diagnostics and dependent-module list when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record type-library LIBID/version and declared coclasses.
- Preserve DllGetClassObject behavior for the expected CLSIDs; it anchors the failure to the real administration object.
Diagnostic sequence
- prove the deployment selected the intended binary.
- The next diagnostic action is to resolve loader and dependency failures before registry changes.
- To isolate this result, compare type-library declarations with implemented class factories.
- rebuild binary and metadata from one source revision.
- rerun InstallComponent and inspect the resulting Components collection.
Difference from nearby COMADMIN results
COMADMIN_E_COMPFILE_DOESNOTEXIST means the file is absent; COMADMIN_E_COMPFILE_GETCLASSOBJ means loading succeeded but class-object discovery failed.
Retry and recovery
Deploy a loadable binary and matching dependencies, then repeat component installation.
Practical administration scenario
The DLL exists but depends on a runtime library missing from the server, so COM+ cannot inspect it.
