Download and install Java if you don't have it installed, if you do open up your downloads folder (or wherever you downloaded the Optifine jar to) and right click on Optifine and click Properties, then set it to open with Java.
I did what jcm2606 said to do,but it didn't have JAVA as an option.What do I do?
Try double-clicking the JAR file with Java installed (make sure you have Java installed!!! I doubt you haven't understood that you have to install Java, but just in case, install it!) and seeing if it opens up. If it doesn't work, open a Command Prompt window in the folder where the Optifine installer is and see if you can run the JAR file from the command prompt (on Windows you can hold the shift key, right click on an empty location within Explorer (not IE, Explorer, the file explorer) and click "Open command window here", you can Google how to open JAR files through the Command Prompt and should come up).

IE doesn't have.... what? Where'd you get the idea that IE has jar files from?
Hey, so. I actually went through the trouble of uninstalling Java, reinstalling Java. And then I set the properties to let the file open with Java. Now, all that happens is a black box comes up for half a second, and then disappears. I set the opening file to "java.exe" and that's what happens. I've tried other Java ".exe" files and they don't work either. Anything you can suggest
i need help, when i try to download optifine it turns into a internet explorer thing ( in the bottom left in my browser )
I know what's wrong..
i had the same problem with my computer..
Windows computers CANNOT open jar files even if you have java..
What you need to do is find the download-win or .exe version to make optifine work.

Well where the hell do you find those. I don't even think they exist.
I am having the same problem. First, I go to the optifine website and download it, it downloads as an EI in the bottom left corner in my browser, how do you download an "exe version" or "download win."
I saw this and then I checked if I had Java, downloaded it again, and rechecked. It said that installation was complete. I had the problem with IE files earlier until I read this post.

I am also having a problem, I am trying to make a server, and I first had the problem that it installed as a IE file, and Now it installs as a .jar- Great! But now when ever I try to run the server, nothing pops up in the folder like the eula or properties, It just opens the cmd.exe and says Error: Can not find or load the main class\User\(my computer name)\minecraft_server.1.11.2. jar and it opens and closes within like half a second. I clicked on it enough times to make out what it said, and i need to know the command prompt that fixed it for you
I have the latest version of java, and I have installed and reinstalled the server, and java, and I have looked everwhere but no one is having the same problem as me, its always a different ending for them.

Hi, I downloaded Java and ran Optifine with it but when I do, a window saying,
Java Installation Incomplete
Unable to install Java
There are errors in the following switches:
"C:\Users\MyName\Downloads\Optifine_HD_U_H6.jar";.
Check that the commands are valid and try again.
