So I really want to download a mod on skydaz.com, but the one I want requires Forge. It's the meteor mod. Ok, so I go install forge. It tells me open minecraft.jar with WinRAR and drag the Forge files there. I open the frorge files and minecraft.jar, but with 7-zip. I copy the Forge files and-nope! I can't paste them in the minecraft.jar. I've done this multiple times and now I guess I'll never get a mod. Is it because I have a Windows XP and no WinRAR? Or is there another solution? Help, please.
