I keep watching videos on how to download Optifine, and I can do everything except for one thing. When they move it to the desktop, it looks like a normal icon with the Optifine thing, and it just says Optifine. I'll do the same thing and it'll be a zipped folder, and it'll say all the information next to Optifine. And then, when they move onto the next step, which you open it into a launcher, the only option I have to open it with is some sort of Java thing, and it won't even open anyway. This is really complicated for me for some reason. Any help? Steps? etc. Thanks!
