Yes, I’m having the same problem. I did a reinstall of both WoW WW and that didn’t work. So, I did a reinstall of both the game and the Blizz launcher. That fixed it for one run. When I tried to log in again it goes back to claiming there is some update and when I tell it to update, I get the error message.
I opened a ticket on this hoping that tech support might help. I’ve not heard directly from them yet. However, what seems to be an auto responder sent a message back stating to check a support page and it provided a link to the page. The page didn’t really address the problem. So, I replied to tech support. We’ll see if I hear back from them.
I don’t know if there is actually an update since I redownloaded the game it would/should have contained all of the latest updates. Additionally, the numbers for the client version and also the Blizz launcher version appear to be current (version 11.0.5.57689 and launcher version 2.38.015147 with an update agent version of 2.37.0.8956).
24 Hour Update
So, after spending an exhaustive time with “tech support” this issue was not resolved. Their final suggestion to me was basically, “well, we’ve done all we can, you’ll have to seek out local assistance or check in the forums.” Needless to say my end survey wasn’t very nice. I will say that the people I messaged back and forth with did seem pleasant and polite, so no ill towards them. However, tech support is not what it once was, not in the slightest.
In any event, I might have found a solution, not that this is going to help others with the problem but, I thought I’d put this up here so some might benefit from it. I should also advise that I’m not sure it’s a permanent solution.
I was running the Beta installer and had been for ages. I switched back to the standard Battle.net installer and the problem resolved. What I’m not sure about is whether the installer was causing the issue, or if somehow something got jammed up during some update at some point and began this mess and thus, when I moved back over to the standard version, it somehow cleared the jammed update request. In any event, I seem to be working again. I wish the best for the rest of you having this issue.
