We're also trying to automate the installation of DDM via Microsoft Intune app package definition.

On specifying the installation command of ddmsetup1995.exe /silent, we saw on the target computer running the processes ddmsetup1995.exe and ddmsetup1995.tmp just hung 0% CPU for a very long time, and still there long after Intune considered the installation attempt failed.

On trying out on my laptop the options /silent, /verysilent, /suppressmsgboxes, I found that no matter what it'd pop a UAC prompt for permission. Even if I approve that, it'll see show the regular installer wizard UI. Beyond UAC, I don't think those options work for the latest version installer?

And given the UAC prompts, can DDM truly be installed automatically in the background?
