Played During the Beta — Error 3014

Technical Support
If you participated in the Diablo III beta, we recommend removing all Installation Files before attempting to install the retail client. You may remove the game files using the Uninstall Program features in Windows (Add/Remove programs if you are on Windows XP). After uninstalling the game, browse through your hard drive and ensure that the following folders have been deleted:

C:\Program Files\Diablo III Beta

or if you installed to another location, make sure the game folder is deleted.
