I am trying to install WoW Wotlk from download off battlenet. I keep getting this error message " No installer data could be found. If this problem persists, please contact Blizzard Technical Support."
I have installed it before, but deleted it.

Hello Menlina,


Looks like you have old WoW and BC files and you are trying to install WotLK on top of all that:

Install/Reinstall WoW - stop working so hard

Try the following to get you past this: go to your Mac HD => Users => Shared and delete the Blizzard folder and now run InstallWoW.app to see if you can get the game installed.

Let me know what happens.
