4 years ago The easiest fix is to just go with a different launcher like the gdlauncher.
It is possible to fix it by downloading and installing forge and moving the missing files from there into the twitch installation.
Tried to download it from the twitch client, and got error "The system cannot find the file specified" when it was done trying to validate files.
No matter what version I tried downloading it gave me this error. Any other mods works fine.
