iTunes - "dnssd.dll was not found"

[james.elswood]

The error message "dnssd.dll was not found" appears when attempting to push out a deployment of 12.12.5.8(x64) through SCCM.

Retrying the installation and on different devices produces the same error, it will only install manually.

Hi James,

You emailed in to support directly referencing this thread. I'm replying here with the same information for completeness.

This is a known issue if iTunes is installed without Bonjour.

Annoyingly, installing iTunes silently does not automatically install Bonjour. However installing iTunes manually via the UI does install Bonjour. Therefore ensure you have the dependency configured on the ConfigMgr App to install Bonjour first.
