No, just Windows Defender, and I've tried shutting it off and downloading. I've also tried shutting off the firewall, made no difference. However, I did try one more time late yesterday using the link you provided above and a DL manager I found in Win Store. Its been downloading 15 hours or so now and shows 57% complete. This is the longest its gone before ending prematurely.
I guess I don't see how I can do anything else since yesterday I downloaded MS Office 365 with no issue, also can download DP client from EU pretty quickly. So....
