Installing Forge (1.17.1)

[Mendaxx]

Hello. I'm trying to install Forge for things like mod support and modding capabilities, and I downloaded here through the site. But when I install Forge, it does install as a .jar file, but when I open it, it acts like a WinRar Archive. I extracted it to a separate folder and everything, but there's is nothing for me to run. Is there a tutorial I can go through to be able to install Forge? I haven't seen any around, and all of them mention opening the installer, when I can't, since it acts like a zip file. Any help here?

Thanks! Jarfix worked wonders for me.
