Here is how to install the Twitch Desktop App in Wine.

INSTALLATION

PREPARE PREFIX

It is highly advised to be using a staging version of wine. Less issues overall.

    WINEPREFIX=/home/user/path/to/prefix WINEARCH=win64 wineboot
    WINEPREFIX=/home/user/path/to/prefix WINEARCH=win64 winetricks corefonts
    WINEPREFIX=/home/user/path/to/prefix WINEARCH=win64 winetricks dotnet46

INSTALL TWITCH APP

To install Twitch, execute the following :

    WINEPREFIX=/home/user/path/to/prefix wine TwitchInstaller.exe

This will eventually complete. Pay attention during the installer to where it wants to install ("C:\users\username\Application Data\Twitch"). I change it to another location ("C:\Twitch").
