Hi,I get the same problem.I'll try to recount my PC statistics,but I also got this with my old PC.It was downloading before I updated BYOND,but when I downgrade it doesn't work anymore either.
BYOND build:4.5* (the new one)
Operating System:Windows 7
Graphics card:It's one of those ones that are really just crap knockoffs.I can't exactly take my pc apart for fear it may not work after,but I doubt it's a card problem.If you still need it I can look into it further.
Internet connection type:DSL
Firewalls/Routers:Configured to allow BYOND through.
Error description:Starts download of BYOND game then stops with error : Error:Unzip failed!
Steps to reproduce problem:Download any game via hub.
