COMADMIN_E_CAN_NOT_EXPORT_APP_PROXY
Exporting COM+ applications and proxies: exact meaning of COMADMIN_E_CAN_NOT_EXPORT_APP_PROXY
The selected COM+ application proxy cannot itself be exported. ExportApplication classifies the target as an application proxy rather than a server application suitable for proxy generation or package export.
Windows describes this condition as “Application Proxy is not exportable”.
Evidence to collect before repair
- Record application ID and type.
- Preserve component install-versus-import provenance; it anchors the failure to the real administration object.
- Evidence should include interface/type-library/proxy-stub metadata, captured before a repair changes state.
- Collect export options, destination path, and ErrorInfo when diagnosing this result; without it the symbolic HRESULT is underdetermined.
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, record application type, source machine role, original server application, and requested export options.
Diagnostic sequence
- To isolate this result, resolve the server application on its owning machine.
- Verify components were installed with complete metadata.
- select package versus proxy export intentionally.
- The next diagnostic action is to use a writable clean destination.
- To isolate it, inspect the produced package and test on a controlled target.
Retry and recovery
Export the server application on its owning server or retain the existing proxy package; do not chain proxy exports.
Practical administration scenario
An administrator connects to a client machine and attempts to export the installed proxy as though it were the server application.
Difference from nearby COMADMIN results
COMADMIN_E_CAN_NOT_EXPORT_SYS_APP blocks the System Application, whereas this code blocks an application proxy.
