STATUS_CANNOT_LOAD_REGISTRY_FILE
Hive loading failed before the key tree became available
The loader could not obtain a valid writable hive image from the specified file and its recovery companions. The primary hive may be absent, corrupt, inaccessible, or paired with unusable log or alternate data.
A manual RegLoadKey operation also requires a supported root and elevated backup/restore privileges. Therefore diagnosis must separate file integrity from path, access, and privilege errors instead of assuming every occurrence is corruption.
What to inspect
- Confirm the resolved file path and that the file is present and readable.
- Inspect the companion log files and preserve them with the primary hive.
- Verify SE_RESTORE_NAME and SE_BACKUP_NAME for manual load workflows.
- Use a known-good backup if structural validation or recovery continues to fail.
