How to Install OptiFine Patch 1.12.1 for Minecraft
The Simple Way (For OptiFine 1.6.2_C4 and newer)
Double-click the downloaded JAR file to start the OptiFine installer
- Click 'Install'
- OptiFine should get installed in the official Minecraft launcher with its own profile, 'OptiFine'
- Start the official launcher and play!
The Complex Way (All OptiFine Versions)
If the above method doesn't work for you, or you're running a version of OptiFine that's too old to be compatible with the instructions above, here's another way you can get it up and running in your Minecraft game.
- Use the official launcher to download and start Minecraft 1.6.2.
- Go to the Minecraft base folder (shown in the official launcher when you click 'Edit Profile' and 'Game Directory')
- Go to the 'Versions' subfolder
- Rename the '1.6.2' folder to '1.6.2_OptiFine'
- Go into '1.6.2_OptiFine' subfolder
- Rename '1.6.2.jar' to '1.6.2_OptiFine.jar'
- Rename '1.6.2.json' to '1.6.2_OptiFine.json'
- Open the file '1.6.2_OptiFine.json' with a text editor
- Replace 'id':'1.6.2' with 'id':'1.6.2_OptiFine'
- Save the file
- Copy the files from the OptiFine ZIP file in '1.6.2_OptiFine.jar' as usual

- Start the official launcher
- Click 'Edit Profile'

Installing OptiFine to Minecraft with Forge
There is a slightly different process for those of you attempting to install the OptiFine 1.12.1 update if you've got Minecraft with Forge installed. It goes like this:

- Remove the META-INF folder from 'Forge9.10.X.Y.jar'
- Start the official launcher
- Select profile 'Forge'
- Click 'Edit Profile'
- Select the checkbox 'JVM Arguments'
- In the field next to it, add: '-Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true'
- Click 'Save Profile'
- Click 'Play' or 'Login' to start the game.
If only 'Play Offline' is available, then log out and log in again to fix it.
