I have an existing Provisioning Machine that was cloned from "Parent" VM and removed Agents, apps, etc and it works there. I checked Distributables installed among other software from base and nothing sticks out. I have no idea as to why it works on that Provisioning machine, also running App Volumes Agent 2.15. I have a ticket open w/ support now and they have had me go as far as bare metal Windows 10 1803 nothing other than agent installed and still fails when in PROV mode.
Now they are asking me to remove all Windows Updates installed to date. SMH
