The newest version isn't installing. I click install and restart the launcher and the version isn't there. It is in the versions folder though

Do you have the "target version", like vanilla 1.11 or 1.11.2 installed?

Are you using the new launcher or the old one?
Which version of OptiFine are you using?

Hello I installed the better fps with optifine 1.11.2 and when I open the launcher it does not enter the game. What do I do?

@PedroOtavio14 What versions of BetterFps and OptiFine are you using? Can you send me the logs from the launcher?

@PedroOtavio14 Optifine 1.11.2 HD U B7 is for Minecraft 1.11.2. BetterFps 1.3.4 is for Minecraft 1.11.
You should download the right mod version for the right game version.

Can you pass me the link of BetterFps 1.11.2? Why can not I find it to download

@PedroOtavio14 Here. Version 1.4.1 for Minecraft 1.11.2. It's currently beta, so stuff might be unstable.
If you find any bugs, please, report them :)

I'm using the
OptiFine 1.11.2 HD U B7 and BetterFps-1.3.4
