COMADMIN_E_SERVICENOTINSTALLED
COM+ service-backed administration: exact meaning of COMADMIN_E_SERVICENOTINSTALLED
A Windows service required by the requested COM+ operation is not installed. COMAdmin reaches a service-dependent operation such as application-as-service management and cannot find the service registration.
Windows describes this condition as “The service is not installed”.
Where the result occurs
The operation depends on installed Windows/COM+ service infrastructure, not merely on the presence of an application object in the catalog. In the specific case of this result, record the requested operation, service name, SCM query result, Windows feature state, and whether uninstall was partial.
Evidence to collect before repair
- Evidence should include service name and Service Control Manager state, captured before a repair changes state.
- Collect installed Windows features and COM+ service events when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record requested COMAdmin method and application activation type.
- Preserve recent servicing, uninstall, or restore activity; it anchors the failure to the real administration object.
Diagnostic sequence
- verify the documented service is installed rather than creating it manually.
- The next diagnostic action is to repair the corresponding Windows feature if missing.
- To isolate this result, reconnect COMAdmin after service repair.
- reapply application service configuration.
- test startup and activation with event logging enabled.
Difference from nearby COMADMIN results
COMADMIN_E_START_APP_NEEDS_COMPONENTS concerns application contents, while this code identifies missing service infrastructure.
Retry and recovery
Install/repair the supported Windows or COM+ feature and rerun configuration; do not create a placeholder service manually.
Practical administration scenario
Automation configures a COM+ application to run as a service on a host where the required service registration was removed.
