Hi ! You're on the wiki for Wii U Cafe SDK Deluxe. In the next months, there will be tutorials about using the tool and making game with Wii U Cafe SDK Deluxe and Unity 2017.
There are no tutorials for now. To install Wii U Cafe SDK, Unity and Wii U Dev Kit, please refer to this tutorial
Here is a list of known issues in Wii U Cafe SDK Deluxe
"This software cannot be used. The Nintendo Network ID used to purchase" when installing or running it on a Wii U
This issue was reported by Antonios Papadakis (also known as one-and-only).
This issue is caused by TitleID. But there is a fix : You need to have the same TitleID in Unity Project Settings, under Player Settings -> Other Settings ->Application section. You have a field named "TitleID (hex)". This needs to match both in Unity and Wii U Cafe SDK Deluxe. You can fill it randomly, but needs to match HEX Format (only 0 -> 9 digits and A -> F letters, and 16 characters long). After making one, check with Title Database - Wii U Brew if your TitleID does not exist (search it with Control + F on Windows or Command + F on Mac).
Note : I don't recommend you to use the default one from Unity and Wii U Cafe SDK Deluxe, when you have multiple projects : Project A : Already installed on Wii U unit. Project B : You want to install it to test it If both have the same TitleID, when installing Project B to the Wii U, files of the Project A will be overwritten to be replaced by the Project B files !

This issue is not currently fixed. I personally don't have it with my example project. I will investigate
