ERROR_SXS_INCORRECT_PUBLIC_KEY_TOKEN
ERROR_SXS_INCORRECT_PUBLIC_KEY_TOKEN — The public key token in the identity does not correspond to the specified public key.
The manifest identity includes a public key and a public key token that do not match. Side-by-Side uses this information to bind to a specific signed assembly, so the mismatch is a package-integrity or manifest-generation error.
Use the original signed assembly and the manifest generated for it. Do not copy a token from a different version or publisher.
What to check
- Identify whether the mismatched manifest is an application-private file or a Windows component.
- Reinstall a trusted version of the application or runtime that owns the assembly.
- For build pipelines, regenerate manifests from the final signing key and output files.
