COM+ catalog object and collection state: exact meaning of COMADMIN_E_NOTDELETEABLE

AllStat records this condition as “The delete function has been disabled for this object”.

Evidence to collect before repair

  • The COMADMIN_E_NOTDELETEABLE investigation needs object key, collection, parent AppID, and deleteability metadata so the exact failing boundary remains reconstructable.
  • For COMADMIN_E_NOTDELETEABLE, preserve system/preinstalled status and object dependencies; it anchors the failure to the real administration object.
  • Evidence for COMADMIN_E_NOTDELETEABLE should include the supported uninstall mechanism for the owning application/component, captured before a repair changes state.
  • Collect the selector used by the cleanup script when diagnosing COMADMIN_E_NOTDELETEABLE; without it the symbolic HRESULT is underdetermined.

Where COMADMIN_E_NOTDELETEABLE occurs

The authoritative state is the logical COM+ catalog exposed through COMAdmin collections, not a single registry key or an old in-memory object. In the specific case of COMADMIN_E_NOTDELETEABLE, record object key, collection, system/preinstalled status, dependencies, and collection metadata before considering any workaround.

Diagnostic sequence for COMADMIN_E_NOTDELETEABLE

  • To isolate COMADMIN_E_NOTDELETEABLE, resolve the exact object by ID.

  • At the COMADMIN_E_NOTDELETEABLE boundary, use the application/component installer uninstall path where available.
