There isn’t a lot of advice to give here.
You either have to use an older version TwitchLib.
Or you have to upgrade your operating system.
Using a older version isn’t a good idea since it won’t be up to date with Twitch Changes. Or include relevant bug fixes.
So the best advice is to move from Windows 7 since M$ doesn’t support it anymore.
The third alternative is to build you own solution that doesn’t use TwitchLib.
Staying on an outdated operating system that isn’t being patched anymore is not a good idea and thus the best advice is to upgrade to Windows 10. Not just for this library but for the health of your system.
So TLDR:
- Use old version of library (not recommened)
- Write you own library (you might have to write your own Web Socket library to since it might be the WS lib that is in the wrong)
- Upgrade your OS.
Of the three options, upgrade your OS is the best option in my opinion
Also consider that if you are running the 32bit of windows 7, it’s not that far off hanving various other problems related to that.
