The EXE root path was pointing to the incorrect location.
The /VERYSILENT switch now works.
The only issue I have noticed is that 63 deployements were successful but 13 have failed due to an incorrect function error.
Is there a place where I can see more details on the error?
The read error KB just links back to the ManageEngine support page.
I believe the issue may be due to users shutting down before the config could finish.
They are in retry stage but one has failed
