I looked at the link that it took me to for troubleshooting and it told me to reinstall the game. After uninstalling, I went to battle.net to reinstall the game and whenever I click on the WoW setup file to install it, I get the same message as before. "Failed to extract the required files from an archive."
I don't understand why this is happening when I am installing the game again from battle.net, I'm pretty sure I wiped all the WoW files off of my computer so nothing should be corrupted. Could anyone else help me with this? I'm getting really frustrated.
