I attempted to download the installer with chrome 5 times, each time the browser would either crash or a network error would stop the d/l around 4gb in. So I switched to MEGAsync. It downloaded smoothly first try.
I found the zip in Libraries > Documents > My Documents > MEGAsync Downloads >
From here I right clicked the zip but was not given and Extract All option. I screenshot an image of my options here: http://imgur.com/AXYTBJz
So instead I went to the WinZip option > Extract to... Everything would go smooth until about 3/4's of the way through when an error would occur. Winzip was not able to extract the file C:\Users\mike\Documents\MEGAsync Downloads\WoW Classic\Wow-1.12.1-Setup-3bin (Sorry I forgot to screen shot this initial error) Would you like to keep extracting with out the full file? I'd click Yes and instantly the following error would pop up: http://imgur.com/dqsWXd1
After clicking Yes it would bring me to the final error which popped up as: http://imgur.com/ZhmIxJT
I've attempted this twice now and both times encountered the same error. If anyone could be of help on how to go about this it would be greatly appreciated!
