Issues with Setting up Gamecube Controller

[SoulCorp]

I started off here:

YouTube: How to setup a Wii U Gamecube Controller Adapter for Dolphin Emulator on PC

After that failed to work, I uninstalled everything through the control panel and then stumbled upon this wiki page:

How to Use the Official GameCube Controller Adapter for Wii U in Dolphin

I downloaded Zadig from that page, opened the exe file, and followed the instructions on the wiki page. The driver failed to download for some reason. So I try it again. Immediately, a window pops up saying, "The driver installation failed."
I follow the wiki page to "Problem with Zadig?" and followed the instructions there. Nothing changed. Can anyone help me with this issue?

I was able to reproduce this problem and I've updated the "Problem with Zadig" section in the wiki page.

Does it solve your problem this time?
