From reading other post i have discoved that i need to unistalled my current game and re-installed from another online link (i think)
When i go to install i get this error: "Uninstall.xml" could not be read.
I now have new erro this morning when i click on WOW : C:\Users\public\games\world of warcraft\launcher.exe is not a valid win32 application.
i found the map for WoW and started the game from there, it actually went fine with no error messages, so i could download cata after.
You can download the latest client from the following link.
I'm stuck on the very same problem. Identical in fact. I know how to download the latest client, but can you tell me how to uninstall it first?
I deleted the warcraft folder as told but it was still recognised in my add/remove in control panel causeing the re-install to get stuck on a certain file. so what i did is just search my computer for warcraft and it will find the uninstall.xml file within the warcraft file and you can just delete it manually from there.
hope this helped.
