This contains all of your Minecraft Profiles, which might be your Forge, Fabric and older versions that you have installed. In the bottom left corner is a dropdown menu. Now that Optifine is installed, open up the Minecraft Launcher. Once it’s complete, you can go ahead and close the Optifine Installer window. Optifine will install into your Minecraft directory, and will complete after a few seconds. The only thing to consider in this window is whether you want need to change the install folder location, but in most cases, this can be left alone. Before proceeding, make sure that the Minecraft Launcher isn’t open, as the Optifine profile won’t install. Open the Optifine.JAR file that we downloaded in the previous step, and the Optifine installer will open, which will look like the window below. Take note that this method doesn’t allow the installation of Forge or Fabric mods alongside it, but Datapacks still work. It’s by far the easiest way of installing Optifine.

Scroll further down, to our Forge and Fabric guides instead if you’re using a mod launcher.

Installing Optifine as a standalone is recommended when you only want to play Vanilla Minecraft.
