I tried updating my Java script to the latest version, installed a Minecraft mod, checked my appdata for the Minecraft mods I downloaded, but I couldn't find a minecraft.jar file anywhere. And also I don't really know how to run the Minecraft mod I downloaded. So I really need some help here, and yes, I'm new to this, even though I've played a bunch of vanilla Minecraft. (Which became SO BORING btw.)
So yeah I really need some help, and I tried watching the tutorials, but it never really explained how to get a minecraft.jar file. Do you just make one ,or do you have to find it?
