Have you got another SD CARD you can test? What if you connect back your Flash Drive, are you STILL able to install games without issues? What WUP installer are you using? WUP Installer GX2 or WUPINSTALLER Y MOD? If it's one or the other, maybe try the other?ĭo you have anything else connected to your USB ports on the WiiU besides your ext usb hard drives? Is it just the one game your having issues with installing? have you tried installing another game(s)? Info on how to do this can be found HERE, disabling this function will probably not solve your issue but it does help once you sort out your install to usb hard drive issue. If you haven't already done so, it is recommended to disable sleep mode for attached external Hard Drives.
