WU_E_OL_NEWCLIENT_REQUIRED
WU_E_OL_NEWCLIENT_REQUIRED means the offline scan package uses metadata or a format that requires a newer Windows Update Agent than the client provides.
What to do
- Update the operating-system servicing baseline through the supported method for that Windows release.
- Use a scan package compatible with the target client only when that is explicitly supported.
- Do not modify the offline catalog to bypass the version check, because WUA validates the package and its metadata.
