Hey, I need help with installing optfine. I have all the mods i need except optifine. When i download it onto my desktop and then open the file to install it, the installer quickly pops up and disappears immediately !? I have tried it over and over again and I've reset my Pc and stuff but it still will not work D: It would be greatly appreciated if someone could pm me and we can team view and fix this problem - _Tranquillity
