Same here. I have to unninstall and install every time to play.

It worked yesterday, but today when I turned on the computer, the error came back.

Hey everyone,

I saw many reports here and elsewhere about this .dll missing error. The developers have been alerted and are looking into fixes.

In the mean time, it sounds like reinstalling the Battle.net application may fix it. I found some more information suggesting that extra folders may be in the same location that Battle.net is installed to. If the reinstall doesnā€™t help, please check that location for a Battle.net 13360 and Battle.net.beta.13361 folder. If theyā€™re there, delete them and then run the Battle.net launcher again. If anyone does this, please follow up here with results so we can forward them along to the developers.

mine had 13360 and 13365.
deleted 13360 and tried loading up,
same problem.
deleted 13365, tried loading up,
worked . went right on in to play.
i have closed and restarted several times to make sure
works every time. the folder will have a ( helper dll listed in it. }
i think this is causing the issue.

deleting the folders didnā€™t help, I donā€™t want to reinstall bnet every time I open it. Couldnā€™t they just do a rollback until they figure out what they screwed up?

This could be a way outā€¦ if everyone was impacted by this issue.

Which is not the case.

I think it is best if they try to figure out why it didnā€™t work on the few instead.

Also broken here.

Windows 10 x64 Home
Version 21H2 (OS Build 19044.1586)

Iā€™ve run the bnet installer (without uninstalling beforehand) and thatā€™s let me login again, but Iā€™m avoiding restarting my PC until a fix is confirmed.

I deleted the 13360 folder without reinstalling B_net, and it launches fine.

Hi,

Two players on Europe French forum say that they deleted the Battle.Net.13360 folder and that everything is now working. See here and here.

I hope this helps.

Hey again everyone,

Just got word that the cause of this should be addressed. It does seem that it may not be a retroactive fix in that if there is bad files are remaining, they will need to be manually deleted. The idea is what was shared earlier.

Using file explorer, go to where the Battle.net application is installed. Typically thats: C:\Program Files (x86)\Battle.net

Look for any Battle.net.##### folders here. The ##### is probably going to be 13360 in this case. Just delete those folders and then restart the Battle.net application. A reinstall should not be needed.

Iā€™ll keep this thread open for now to monitor if this persists for anyone. Thanks Boubou and everyone else for the updates and patience while this was sorted out.

Had the 13360 folder in my install location, deleted it and bnet launches fine now, including after a system restart.

Did you remove the 13360 folder? Fixed it for me without having to reinstall.
