My laptop jerks a bit when I play Minecraft. That's why I wanted to install Optiefine. But it always says Access denied File not found. What should I do there?

un

Do you have java installed?

Bi

Yes of course I'm not stupid, maybe I have to drag Optiefine into the version folder or something

un

If you have the latest version of Java installed, the file should open an interface after double-clicking, please make sure that you have selected the .minecraft folder there

Bi

The problem with the interface doesn't come

un

Does the optifine file have a .jar extension and is the icon of the file a Java mug?

Bi

Yes

un

Try right-click and open with java

Bi

OK
