ERROR_SXS_PROTECTION_CATALOG_FILE_MISSING — The catalog file required to protect a Side-by-Side assembly is missing.

Windows found an assembly reference but could not locate the catalog file that verifies it. The installation may be incomplete, the component store may be damaged, or files from different package versions may have been mixed.

The correct repair depends on ownership: reinstall a private application package, or use Windows servicing for a system assembly.

What to check

Use the SideBySide event or sxstrace output to identify the assembly and catalog path.
Do not download a catalog file separately or copy one from another machine.
For a Windows component, use DISM and SFC to restore the component-store relationship.

DISM /Online /Cleanup-Image /RestoreHealth

sfc /scannow

Microsoft: sxstrace
