This is expected in the following circumstances:

If you are installing this update on a device that is running an edition that is not supported for ESU. For a complete list of which editions are supported, see KB4497181.
If you do not have an ESU MAK add-on key installed and activated.

Additionally, text stating "An account with the same name exists in Active Directory. Re-using the account was blocked by security policy" might be displayed.

Affected scenarios include some domain join or re-imaging operations where a computer account was created or pre-staged by a different identity than the identity used to join or re-join the computer to the domain.
