Yep, downloaded from the right website, but, when i go and click "Open With" there isnt anything involving java, which is the way ive seen it done. When i do download optifine, the file takes on the 7-Zip icon. I think that is my fault, i may have accidentally clicked 7-zip as the default program when dealing with.jar files, but that shouldnt affect The "Java Platform SE Binary" option from not showing up :/
