If these are corrupt, WoW will not be able to launch.
Corrupt Configuration files: World of Warcraft has configuration files saved on your computer which provide the initial instructions to the computer on how to load the game and on which parameters.This is very common and can occur if an update went wrong or you copied the game from somewhere else. Corrupted Files: Windows and Game files get corrupt or unusable every now and then.If they are not in a working state, the launcher will fail to load them and hence WoW will not be able to launch. Outdated Add-ons: Since add-ons are an essential part of World of Warcraft, it is possible that they are not updated correctly or are corrupt.
