I followed this guide

I've installed the drivers on both 64 and 32 bit versions of windows and it's not showing up on anything like discord, obs, vlc or
virtualdub.
My computer plays a sound when I plug it in but it doesn't show up under my usb devices.
I did get the card used but I don't think there's any sort of drm that won't let you use it if the serial number's already been entered.
Some of the stuff is in Japanese but other people have said you don't need to install a language pack for it to work.
I only tried using it with Windows 10 and 8.1, I tried to install Windows 7 but I can't proceed with the installation because I can't find any drivers for my motherboard (if there even were any to begin with since mine's from 2017).
