I have the same error.. with "Wii fit U Release", only extracted system folder with a very tiny size, and content, code and meta is not extracted--- help me please, its unique WUD one what i cant extract...
You need the x86 version of the Visual C++ redistributable to extract game files. The error message that is not being displayed is related to a missing dll (MSVCR120.dll). https://www.microsoft.com/en-us/download/confirmation.aspx?id=40784
search and install...
MSVCR120.dll in system32 folder and you will be good to go!
Sorry about that. I didn't know it was against the rules to post the keys.Anyone know a fix, other than the steps explained in the prior comments? I checked and i already have the msvcr120.dll file in my windows 10, windows/system32 folder. even installed the windows x64 visual basic c++ pack. still get the message, "invalid argument" and yes, i have 32 characters for the game's key. I created a key.bin from the title key. The Uwizard program shows all green in the title key field and in the settings, where 3 keys need to be entered. All show the validated color Green.
