COMADMIN_E_APP_FILE_VERSION
COM+ application package and file operation: exact meaning of COMADMIN_E_APP_FILE_VERSION
The application file uses a version that this COM+ installation does not accept. Package validation succeeds far enough to read format metadata and then rejects the declared version.
Windows describes this condition as “Invalid version number in application file”.
Where the result occurs
The HRESULT belongs to COM+ package/import/export processing; the package path, file bytes, deployment identity, and target catalog must be correlated before changing the system. In the specific case of this result, record source and destination Windows versions, export options, package hash, and whether compatibility format was selected.
Evidence to collect before repair
- Preserve exact source/destination paths and the caller identity; it anchors the failure to the real administration object.
- Evidence should include file size, hash, version, signature, and timestamps, captured before a repair changes state.
- Collect source and target Windows/COM+ versions when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record underlying file-system or package-validation error from events.
Diagnostic sequence
- Preserve the original package before attempting repair.
- validate path access and package integrity under the actual identity.
- The next diagnostic action is to compare export options and target-platform support.
- To isolate this result, regenerate the package from a coherent source application when metadata is wrong.
- Repeat the complete supported install/export operation and verify catalog state.
Retry and recovery
Re-export with a format supported by the target or deploy to a compatible platform; repeated installation of the same file is deterministic.
Difference from nearby COMADMIN results
COMADMIN_E_APP_FILE_READFAIL indicates unreadable content, whereas this code identifies a readable but unsupported application-file version.
Practical administration scenario
A package exported on a newer server is installed on an older host whose COM+ catalog cannot interpret the package version.
