Wow hangs on updating blizzard launcher
Follow this link for a complete list of ports: https://eu.battle.net/support/en/article/firewall-configuration-for-blizzard-games Second of all, I assume you are rejoining in the Mist of Panderia expantion.
An update to the Blizzard launcher and associated tools this afternoon has been causing problems for folks running various versions of Windows.
The bug has a chance of occurring when you get stuck at a "Waiting for files to close..." dialog box when updating.
I did some additional googling and found a post on a blue tracker which simply advises to perform all of the steps I have already run through.
For whatever reason, Internet Explorer (which I never use) was set to "work offline".
I have downloaded the installer with no problems and run it as administrator, however it simply hangs at "Checking for updates..." as per below; I have left this installer for a period of time and it has not timed out, it simply just sits there doing nothing.
While I was investigating a similar issue for Diablo 3 (which got several steps further than this issue), I have already completely cleaned the World of Warcraft agent from my machine, and rebooted multiple times in an attempt to get this installation process to progress.
