I have done that also the problem still persists and I’ve added all exclusions to bnet and the agent Kaspersky isn’t reporting anything in its logs to suggest that it’s blocking the agent from functioning? And if so wouldn’t the logs say that when attempting to connect? Like connection denied? Also wouldn’t the anti virus block other attempts to download like overwatch?
I decided to go scorched earth. Uninstalled wow and the battle.net launcher. Also deleted the battle.net and blizzard entertainment folders that were located in the programs data folder.
I was going to reinstall everything on the same drive but decided against that and put it all on another drive because its been far too long to get this working again. Wow is still downloading but the play button is back.
I will launch the game after everything in done downloading to play it safe and report back.
Edit: That seems to have fixed my issues. Not sure if it was both deleting everything and installing on another drive or just one of these that did it but worth noting.
I just tried this with completely disabling my anti virus with no success.
I even uninstalled my AV and the same problem continues to happen.
I tried Bnet and on my 2 hard drives and my SSD and it’s still looping…
Updated antivirus… no change.
Disabled antivirus… no change.
Disabled VPN (with AV enabled and disabled)… no change.
Created a new administrator account in Windows 11… no change
Repeated all previous steps and combinations of steps while logged in to new admin account… no change.
Uninstalled Battle.net app, including all indicated folders, reinstalled Battle.net app… no change.
Attempting to launch Retail WoW via WoW.exe results in an error:
The CAS system was unable to initialize: Unable to initialize CAS from build info file. No active install info entries.
Unable to initialize CAS from patch service: provided version info string(s). VersionInfo: us. CDNInfo: us
Attempting to launch either Classic Era WoW (WotLK Classic) or Classic WoW via their respective WoW.exe files
results in an error:
Your World of Warcraft installation is damaged. To learn how to repair it, see: https://battle.net/support/article/6572
Following the steps described in the above article results in a repeat of the initial complaint (Update and Scan & Repair both fail with ‘something broke’ error code BLZBNTAGT00000BB8.
TL;DR–
Original admin account, VPN on, AV on - fail
Original admin account, VPN off, AV on - fail
Original admin account, VPN on, AV off - fail
Original admin account, VPN off, AV off - fail
New admin account, repeating the above four states - all fail
The only thing I can think to do at this point is to uninstall and reinstall all 3 game clients and try again.
Update - Uninstalling and reinstalling the game clients resolved the issue. Not sure uninstalling/reinstalling the Battle.net app a second time was necessary, but it was at least a quick download and install.

I don’t fully know what I did but it’s now working the last thing was another fresh reinstall which didn’t work till today after I turned my computer on my pc for the day.

Funy as of about 10 min ago this issue resolved on its own. every day for 8 days I would try to reinstall with the same loop. Once it failed, I uninstalled, deleted all retail files, and continued on to WOTLK. It was only retail where I had the issue. So just a few minutes ago, I began my same ritual, and what do you know…its downloading. So All of the troubleshooting steps suggested I did, as well as quite a few others. Even as far as formating the NVME that I store my games on. My money says its a Blizzard issue that only pops up in certain configs. Not sure though. Considering that others seems to be experiencing the same miraculous fix…I’m going with Blizzard ninja fix.

None of this is related to A/V.
This is a problem with Blizzard’s client and update process, full stop.
You should be collecting diagnostic information and opening an internal issue/bug-report for your dev team, not telling a myriad of people with the same symptoms that suddenly they all magically have system corruption or antivirus problems at the same time.
Maybe working in software development for almost a decade has given me a different perspective, but when you see this type of issue pop up, it’s usually a sign of a problem with your software.

So I had the same issue. I did the following:
- Uninstalled all Blizzard content
-Deleted all Blizzard registry entries - cleared all Temp files
- Even went as far as to format my Game storage drive
No change.
I had to go into the settings of the desktop app and tell it to use the beta version (not to be confused with the beta files for the game; the actual desktop app beta version) - fixed it.

I know this will help only a few of us, but it finally installed when I closed Malwarebytes. Hopefully that might help someone but I hope its resolved for everyone else.

I started experiencing this issue a few hours ago after being spammed with lua errors in-game with no addons enabled. I conducted a scan/repair thinking that might help but fell into the infinite loop instead. I’ve tried all fixes listed here plus a few others the CoD community came up with when facing the same problem. So far nothing has worked (including the previous post’s fix of disabling Malwarebytes).
This is happening for both live and classic, though not any other Blizzard game so far. I was able to update Hearthstone without any issues.

Just wanted to comment that I’ve been having the same issues since yesterday and I’ve tried everything in this thread. My spouse has the same issues but theirs resolved by uninstalling and reinstalling bnet.

The second plan worked. Got me back running but I lost ALL addons and settings 
progress I guess
for world of warcraft, you need to save the \interface\ and \wtf\ directories and restore them after the scan and update process
I am with you on this Teuf, i am currently re-downloading WoW and going to try again, but its odd for me because i see it downloading in the battlenet window, but the battlenet app does not load to the info screen with all the game options.
Back in the same boat, though just with retail this time. Launch Battle.net, and it says WoW is updating without any indication of anything actually happening. Was hoping to log in and redeem the CE items, but I guess I’ll just let it do its thing and see what’s going after maintenance.
Edit - Of course. Tabbed back over to Battle.net as soon as I posted this, and everything’s behaving as it should.
the second method worked for me, i delete everything except Data folder and and run scan/repair and its done
