Stuck at "Updating Blizzard Launcher"

Technical Support
1 2 3 6 Next
When I try to go into the game from the Launcher, I hit the screen that says "Updating Blizzard Launcher". The bar goes to about 2/3 of the way full, then just stops. The only option I have is to exit the launcher and try again, and the same thing happens.

I think the launcher files may have been corrupted, and I need to get rid of what's corrupted so I can redownload just the launcher.

If I go into the game directly, it works fine.

Try this:

1. Make sure that Windows is set to show hidden files.

Here's how to do that: http://windows.microsoft.com/en-US/windows-vista/Show-hidden-files

2. Navigate to the C:\ProgramData folder and delete the Battle.net folder.
3. Navigate to the WoW folder and delete the "Updates" folder.
4. Launch WoW.

Let me know what happens.

There was no Battle.net folder in the ProgramData folder, even though I have "See Hidden Files on" (I can see other hidden files and folders)

I deleted the Updates folder, but the issue persists.
And BTW, this computer runs on Windows XP if that helps.

OK, deleted the battle.net folder (there were other folder there that seemed to be related to Blizzard games I didn't delete) and the Update folder. Still having the issue of getting stuck 2/3s of the way through the bar before getting into the Launcher.
Boffo

Go into the World of Warcraft/Data folder and delete the Cache folder in addition to the Updates folder and try again.
