I wrote a script to create a symbolic link to fix this incredibly stupid problem. I do not want the client installed to the same drive where I keep my games or use the default folder that Twitch requires. With the link I can redirect it to whatever folder I want. Run the following from an elevated command prompt. The destination folder I used can be changed to whatever is needed.
rmdir "C:\Program Files (x86)\Twitch\Games Library"
mklink /D "C:\Program Files (x86)\Twitch\Games Library" "J:\Games\Twitch"
