Installations via InTunes failing but work from SCCM

We have pretty much completed our migration from using SCCM to InTune (IT).

However, we are encountering a few apps which hang at certain points during the installation. These have worked 100% falwlessly through SCCM and indeed, if we revive the SCCM deployment, we can install via that route.

I strongly suspect that IT is handling output (STDOUT?) differently than SCCM does, wherein the installer is trying to display a screen but cannot and so just hangs indefinitely.

Aside from the above return-to-using-SCCM work-around, we have occasionally resorted to repackaging the offending installer but this obviously introduces a delay in getting apps deployed to our user-base.

Is there some flag we can set when adding apps to IT that we're somehow not seeing, or some other configuration we set - maybe at the client-level - to bypass this behaviour?

If you feel like experimenting, grab the Innorix Agent installer which is one that's causing us grief presently.
