I got Optifine HD for minecraft 1.11.2, it installed smoothly and really fast, I went in Minecraft and I clicked the "Play" Button, It went fine, but it didn't launch the game, it just made the "Play" Button clickable again.
The exact same thing happens to me whenever I put a forge or optifine profile directly in the versions folder. Are you using optifine as a profile or a forge mod. If you are using it as a forge mod, try reinstalling whatever version of forge you are trying to use. If you are using the profile version, same goes there. Just reinstall it by running the jar file again. If that doesn't work, you can try reinstalling minecraft like Greymagic27 suggested. Make sure you drag your saves folder and any resource packs and shaderpacks you may have installed out of the .minecraft folder, then just delete the .minecraft folder.
