......Well yes, probly shoulda said I have Forge on there already. And I'm trying to install it onto another folder I already have; tried once to extract onto said folder, and it basically just duped the installer; tried moving it from the .minecraft folder to the other folder, and it lolnoped the mod when I started it up.
Because I used to be able to use it in a different folder, just like any other mod? I've used Optifine before on previous versions, and I did not have to go through all of this iirc. Which is why I'm really confused, here.
