As of yesterday I have not had access to my TBC Classic account because it keeps telling me to update… which then fails. I have tried to Scan & Repair my files… Yet this seems to have only perpetuated the issue somehow, as has simply resulted in NEW error messages.
Today I uninstalled and reinstalled TBC Classic… YET THE PROBLEM PERSISTS!
Constantly showing pop messages that the client is updating… and asking for permission to alter my desktop data. (Which I allow every time it happens)
I am at a loss… Please. Any help is appreciated. Best regards.
@Daewryen: If you are getting specific error messages, then writing them down and adding them here could help. I am also currently in a limbo with all 3 versions of WoW, but I am not getting any error messages at all, the launcher simply scan & repairs in a loop again and again.
I am in the exact same position! I have been having random disconnects from the game and wanted to try a reinstall. Now I cannot access the game.
I am getting this: BLZBNTAGT0000096A
I have unistalled battle.net completely and reinstalled. Tried to reinstall Classic and here we are again. Saying I need to update but not being able to.
Please save me Blizzard
Close battle.net - open wow folder, data folder, 2nd data folder, delete all the .idx files, including shmem.
re-open battle.net, let it repair and update, and it should be ok.

@Bèétlejuice: Thank you for trying to help, but at least my computer just created a bunch of new .idx files (and shmem) and the looping continues.

Try deleting all files of 1kb in size in mentioned data folder.
Then run scan and repair

This is a bit of a long shot, but could people please check which exact directory the game is actually installed in? There are a few places within the Windows default folder structure where such issues tend to occur with rather high frequency (e.g., anything in \Users, \Documents…) - having the game installed in a folder like “C:\Games\WoW” is often the best solution.

@Healarius: That finally did the trick, after I deleted all files in that folder under 1600 kb simultaneously. Funnily enough, a few of the replacements are still tiny. In any case, thank you!
@Veadsarias: My installation is directly in D:\World of Warcraft so at least in my case path complexity was not the reason. In any case, thanks to help, all 3 WoWs are back to normal operations.
