STATUS_MUI_FILE_NOT_FOUND

The selected language resource file could not be found

Windows MUI separates language-neutral executable code from language-specific .mui resources. The loader searches language folders according to the application, user, system, and fallback language lists. This status means no usable file was found at the expected point in that search.

A missing file can result from incomplete language-pack deployment, an incorrect directory tag, a renamed base binary, or packaging that omitted the matching satellite resource. Copying an arbitrary .mui file from another build is unsafe because MUI validates its association with the language-neutral module.

What to inspect

Record the language-neutral module path and the ordered language fallback list.
Check the expected BCP 47 language directory and exact .mui filename.
Verify that application and language resources were deployed from the same product build.
Use MUI resource tools to inspect association data instead of renaming unrelated files.
