Failed to read a required file...

I'm having issues on a Mac.
When you move update file 16016 to the desktop, it just reunpacks it from the installer file...
Then it tries to initialize, lasts all of 30 seconds before stating that it failed to read a req'd file.
Deleting WTF folder really didn't change anything either...

And the only reason I'm here specifically is because my game wouldn't update to the new content (would freeze at around 7%) and I figured a fresh install would fix it. Guess not

Almost a month and still not 1 blue post on this error? Absolutely pitiful.

IMPORTANT MESSAGE:
-I fixed it!-

Some of you won't like this route, but it works.

Concerning Addons/Macros:
I know some of you might be worried, that your addons won't be set up the same when you reinstall. I assure you, most of your previous macros/addon's, are redundant; because the new class/spell setup causes them to become obsolete.


  • 1)Uninstall the whole game, and erase all related files.
  • 2)Install CCleaner onto your PC, and do a registry clean. (Deleting/Cleaning all WoW registry entries leftover in your computer; plus other OLD registry crap slowing down your computers.)
  • 3) Download the newest client, and it will download/install/patch to the latest version.
  • 4) Log on, and feel the relief of finally being able to play again.


  • Also, for anyone who hasn't played MoP yet, or the beta; your classes are quite different to play now. Expect a big change, but, it's actually quite a fun change.

    Not sure if the solution has been posted yet:
    (not even thinking of reading through 16 pages lol)
    I just installed windows 8 from scratch and encountered the same problem when installing.

    However the following worked for me:

    Goto:
    C:\ProgramData\Battle.net\Setup

    delete the folder:
    "wow_enus"

    Run setup again.

    fixed mine doing this: (im on windows 7)

    Go to C:\ProgramData\Battle.net\Agent\Agent.1267\Logs
    (Check first if Agent.1267 is the latest number on C:\ProgramData\Battle.net\Agent\folder)

    Search for a file called something along this lines:
    AgentErrors-20120831-185711193.txt
    (repair-on-demand.txt may also reveal the damaged file)

    Open it a see if it says the name of the file thats causing the error, in my case it said this:
    #-----------------------------------------------------------
    # System started at 2012-08-31 17:57:11.1930
    # system: RandomNoobs-PC
    #-----------------------------------------------------------
    17:57:25.0314 Patch Application Initialization - Failed to open archive 'W:/World of Warcraft/Data/wow-update-base-16016.MPQ'
    17:57:25.0316 Updating Error: 2111

    Notice the file name where it failed to open, what i did next is pretty simple, i went to that folder and renamed the file extension (you can cut it off if you want but a rename will do)

    Try to re-run the launcher now.

    **** all credits go to Knigthmare (Undead Priest of <AwoL> Stormscale (EU)) for the fix ****

    I right clicked the launcher .exe file and ran as Administrator. This worked for me.
