ACCC app downloads_then stalls on Update

I am trying to come up to current apps in a prepress environment. Have been able to do direct downloads on PhSh and Illy, but these are not available for Acrobat pro DC or InDes, AFAIK.

Downloaded the 251 MB ACCC app no probs., but then on launch it goes straight into an Update pane, and sits on 1%.

We are in Australia, if that makes any difference.
