Download doesn't complete

Trying to install Scapple for Windows on a new machine.
The download just dies after 40% (20 megs of 49.6).
Once it reaches that point, no more data is sent and whatever tool I’m using to perform the download eventually times out with a failure.
It fails at 40% with Chrome, Microsoft Edge, and curl.

The URL in question: http://scrivener.s3.amazonaws.com/Scapple-installer.exe

My apologies, it apparently has something to do with my company’s firewall. Please disregard.
