COMADMIN_E_CAN_NOT_EXPORT_SYS_APP
Exporting COM+ applications and proxies: exact meaning of COMADMIN_E_CAN_NOT_EXPORT_SYS_APP
The COM+ System Application cannot be exported. ExportApplication resolves the special system application and refuses package generation.
Windows describes this condition as “System application is not exportable”.
Where the result occurs
COM+ export behavior depends on application type and complete installation metadata; system applications, proxies, and imported components have deliberate export limitations. In the specific case of this result, log target AppID and name to detect accidental selection by broad enumeration or localized display name.
Evidence to collect before repair
- Preserve application ID and type; it anchors the failure to the real administration object.
- Evidence should include component install-versus-import provenance, captured before a repair changes state.
- Collect interface/type-library/proxy-stub metadata when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record export options, destination path, and ErrorInfo.
Diagnostic sequence
- resolve the server application on its owning machine.
- verify components were installed with complete metadata.
- The next diagnostic action is to select package versus proxy export intentionally.
- To isolate this result, use a writable clean destination.
- Inspect the produced package and test on a controlled target.
Retry and recovery
Export only deployable user applications; document system settings separately through supported configuration management.
Difference from nearby COMADMIN results
COMADMIN_E_SYSTEMAPP is a broader restriction on system-application operations.
Practical administration scenario
A backup script loops over every Applications item and tries to export the System Application with user packages.
Operational exclusion
Exclude the COM+ System Application by its stable AppID from generic export loops. Export only user applications whose deployment artifacts are intended to move between computers.
