What NS_E_MMSAUTOSERVER_CANTFINDWALKER means

NS_E_MMSAUTOSERVER_CANTFINDWALKER (0xC00D0046) means Windows Media could not locate or load the file walker/parser needed for the selected media source.

Evidence to preserve

Capture the source type, parser/walker name or registration expected, server identity, and the load/registration error that precedes this HRESULT.

Interpretation

This points to parser discovery or loading, not to a decoding failure after a parser has already accepted the file.

Recovery and verification

Restore the registered parser component appropriate for the source and verify that the server can instantiate it before retesting the original media.
