Encompass by Ellie Mae, ICE Mortgage

Looking to get a global software deployment of the below software:
Encompass - Loan Origination Software System | ICE Mortgage Technology

PDQ made an article that has some details, but missing just enough to make this a challenge.
How to deploy the Encompass 360 SmartClient | PDQ

Here’s the DOCX that I’ve been mainly working from, which contains dependency URLs and silent flags.
I’m putting work into this currently and have up to the Amyuni PDF converter in a local software object.

I can’t seem to get the installer to fire from system context.
When running from user context, there’s a UAC elevation prompt, which really subtracts from the “silent” part of the deployment. Any ideas?
