Sometimes clicking pause and unpause on the download ui when it stops works for me and sometimes when i do an options scan and repair it reboots the download.
I would have saved uninstalling battlenet as a very last resort.
Don’t shoot the messenger , this does not work 100%, but you might try it see what happens, for lack of something better to do.
Anther thing you can try , is to log in from the battlenet icon in the retail folder and not your desktop. I only experienced it on mac, but somehow the desktop icon was corrupt.
The drive you are installing wow on…
SSD with at least 20% empty and formated NTFS. 150GB … Or 180GB minimum.
Also check your C: drive with windows controlled page file of the same as above.
or more… Controlled by windows.
I even put a page file on the drive I have wow installed on… It was not using the drive.
Pause and restart has worked for me.
I also recommend to try the beta of battle.net as it should fix permissions.
You listen to these tech guys, they know what they are talking about , I only have minor experience and shouldn’t be giving advice.
I discovered the Bnet desktop icon thing by mistake, so it may not work for everything , but I mentioned it cause I wanted you to know somebody cared.
Elocin seems to come in every few days, they know a lot .
I had exact same issue and saw you post before spending hours finding what fixed it
the service Windows Management Instrumentation(WMI) service is the issue.
You have to clear it and reset it and after many hours and reboots as soon as i did that it worked. Came back to this post to let you know in case you are still stuck as this issue was a nightmare to resolve
