Here’s the fix for the “THE FIRE FROM THE SKY STILL FALLS” installation error / problem in Diablo 3.
This URL is redirecting to the wrong address: http://ensg.nydus.battle.net/D3/enSG/setup/mediakey
If you block ensg.nydus.battle.net on your hosts file, it’s possible that the installer will use the second URL, which would allow you to install.
How exactly do I block that on my host’s file? And when I copy paste that URL, I get the error message. I’m assuming that’s what you’re talking about.
I edited my original post to include the URL, but here it is.

put this in your host file to fix it
0.0.0.0 ensg.nydus.battle.net

us.battle.net
ENJOY!
