I just uninstalled the launcher and got a new one, but after it created a new launcher for me, it is still stuck on “initializing” so I submitted a ticket. I also included all those diag and ms files they always ask for and a screen shot of the launcher stuck at the initializing stage.
I was supposed to run some events tonight with my guild…but I can’t even log in.
Can’t log into retail, 10 hour queue on Wrath… remember back in the day when they would credit you 1 day of game time for a 10 minute maintenance?
doesnt tell you what folder to delete in there, there isnt a cache
This worked for me! Thank you.
what folder in there did you delete
It says to delete the entire folder. That’s what I did.
i see it thank you love
Also, be warned. When you relaunch the BNet app, it’s going to act like you never installed the game. Do not install it, choose the link under that to find the install location. Then select the retail folder wherever you have WoW installed.
Did not work 
I tried all solutions offered, NONE worked.
this doesnt fix the launcher
This worked for me. Took some time to figure it out but it works! Thank you!
Deleting program data as suggested works
Worked for me, thanks!!
Same problem here, cant lauch the game
This did work to help me start the beta update, thank you!
Hm. I tried that and it told me the folder (retail) doesn’t contain the correct version of the game.
fix your game already blizzard, cmon!
I’m having the same problem. I went to update the retail version of wow and it got stuck on initializing for over half an hour. I have tried restarting, reinstalling, deleting the battle.net cache folder, running everything as administrator. i have tried everything i can think of. now when i go to reinstall the game it is still stuck on initializing.
Same problem. Glad it’s not just me. I had some concerns.
