Are you using the program and the dll at the same time? That's not going to work. You need to use either the program or the dll.
The dll works stand alone and in fact can't even talk to the controller when the program is running.
Didnt really help.
Maybe I need to install some of the requirements stuff.

You mean I only need the dll and not even your Wii U Pro Controller program?
