STATUS_SXS_FILE_HASH_MISSING

The manifest has no usable verification hash for an assembly file

STATUS_SXS_FILE_HASH_MISSING means that an assembly file lacks the verification information expected by the side-by-side operation. Assembly manifests can provide a hashalg and hash for a declared file; when verification is required, absence of that metadata is distinct from a computed hash mismatch.

Do not invent or copy a hash into an installed manifest without rebuilding the package. The algorithm, encoded value and file bytes must originate from the same trusted build. A missing hash is a metadata/packaging defect, whereas STATUS_SXS_FILE_HASH_MISMATCH means existing metadata did not validate the file.

What to inspect

Inspect the exact file element and determine whether it lacks hash, hashalg or both.
Compare the manifest with the producer's packaged artifact to identify whether metadata was stripped or generated incorrectly.
Redeploy the complete verified assembly instead of editing the component-store manifest in place.
