What does Windows error code 4050 (PEERDIST_ERROR_CONTENTINFO_VERSION_UNSUPPORTED) mean?

PEERDIST_ERROR_CONTENTINFO_VERSION_UNSUPPORTED

The version of the supplied content information is not supported.

PEERDIST_ERROR_CONTENTINFO_VERSION_UNSUPPORTED is Win32 error 4050 (0xFD2) and belongs to Peer Distribution and BranchCache content information parsing.

Troubleshooting steps

• Record the first bytes, declared version, producer OS, and API version.
• Record the exact PeerDist function involved in content information parsing.

What to verify

Verify whether the content-information blob declares a format version the local PeerDist implementation cannot consume. Check the first bytes, declared version, producer OS, and API version; record the exact PeerDist function involved in content information parsing.

Handling, retry, and recovery

Regenerate content information with a mutually supported version or route the request to a compatible endpoint.

Difference from nearby codes

PEERDIST_ERROR_VERSION_UNSUPPORTED concerns a requested API or operation version more generally.

Practical example

A publisher upgraded before branch clients; clients reject the new content-information version while older blobs still open.
