OptiFine uses Java to run its installer.
If you don’t have Java on your PC, the installer won’t open.
- Check if Java is installed:
Press Windows + R, typecmd, and hit Enter. - In the Command Prompt, type:

- Click Play.
When the game loads, go to:
Options → Video Settings — you’ll notice many new options like:
- Shaders
- Dynamic Lights

That means OptiFine is working perfectly!
Step 6 (Optional): Install Shaders for Better Graphics

Safe sites include: https://shadersmods.com/ - In Minecraft, go to Options → Video Settings → Shaders → Shaders Folder.
- A folder will open — copy the downloaded
.zipshader file here. - Go back to Minecraft and select your shader pack.

.jarfile again. - Place it inside your mods folder:
