It's WUPinstaller. WUDs are disc images. Keep in mind that wupinstaller uses the normal system installation function, and Nintendo has built-in features to deal with installation failures. Go into System Settings, then Data Management, just like you would for an eShop game. If you get the message that there's unnecessary data, let the system delete it. If the console hangs for a long time during the delete, force power off (even though it says not to), start back up, successfully install something to that device (system storage or USB) then go back and do the delete again. If you need help with the regular functions of the WiiU, like deleting and moving games, check the electronic manual, or you can ask us in the WiiU Console forum. — Posts automatically merged - Please don't double post! — Let us know the specifics and someone will try to help you.
