I really need help downloading Optifine for any version of 1.8. I was basically told that it would be easier to uninstall WinRAR, so I did. But, when I re-downloaded Optifine, it only opened with Notepad. I have absolutely no idea how to fix it, and on this laptop my Minecraft runs at 4-8fps average so I was hoping someone would know what to do. I've watched YouTube tutorials but that barely helped me. Contact me asap? :c My Skype: tessa_vans

are you using windows, mac or linux? (ubuntu)
Did you get it working?
Thanks very much, I seriously don't know what I would do if weren't for you people at planet minecraft. I know this post doesn't say much but I really do appreciate it. <3
It may not be the same issue, but on a friend and family members computers all I did was install and run JarFix and then try the optifine install again.

Literally what I said...
/me hops onto forge's cloud of happiness
If you are trying to run optifines' auto installer and are still having trouble with changing the file it opens with. Open a command prompt, write "java -jar "(needs the space after -jar) then drag and drop the jar onto the command prompt before hitting enter. This should run with the most recently installed version of java.
Thank you so much man, you really helped me a lot. Without you I would have not been able to play minecraft without lagging. I had been trying to figure out how to get it to work for days but everything I tried just wouldn't work. I was beginning to become hopeless. Then I saw your post, but I didn't expect it to work. I still tried it though, which resulted in me being able to download it. Thank you so much

Well if your Minecraft runs at 4-8 fps I'd recommend not to use Optifine. It will make your game even slower, due to it being more for the computer to handle. And all the mod does is to make the graphic settings more customizable. But if you don't know how to do it already you shouldn't use OF.
A tip, if your computer is slow, use these settings
And remember that Optifine doesn't fix the lag for you
A tip, if your computer is slow, use these settings
Graphics: Fast
Render distance: 2-8 (depends on how much your pc actually can handle)
FPS: 30-90 (also depends on your pc, but 90 is a max! FPS is not about having as much as possible, but to have it stable. SO its better to have a stable 30 fps than fps flacking from 50-130, that'll give you a headace)
Smooth lightning: OFF or minimum
mipmap: OFF
Particles: minimal
VSync: OFF
VBOs: OFF
Clouds: OFF
Fullscreen: OFF
GUI Scale: doesn't really matter, try smaller if it still lags.
Entity shadows, Alternate blocks and View bobbing doesn't really matter either, try to turn them off if it still lags.And remember that Optifine doesn't fix the lag for you
It has happened to forge!!!! What do we do?!
Have you tried deleting system32?
you dont need to suggest something like that, cause if they actually do it they mess their entire system up and you both are to blame for the stupidity

I am having the same issue... I have tried everything... installed java offline, dev java, open with javaw.exe or any other Java option I googled... I am done....
I'd tell you, but I be 2 stewpid
Easy tip for everyone in future, if having .jar files, keep them with Java. For .zip, .rar or .7z, use 7-zip or WinRAR.
Windows doesnt automatically assign java to run .jar programs even after java is installed
Well, not all Windows Computers. Mine did. But if it doesn't, it is best to assign them to Java.
Make a file in Notepad with the following:
Where Optifine.jar is whatever the Optifine JAR file's name is. Save it as install.bat, put it in the same place as the Optifine JAR, and run it.
@echo off
java -jar Optifine.jar
Where Optifine.jar is whatever the Optifine JAR file's name is. Save it as install.bat, put it in the same place as the Optifine JAR, and run it.
Ah, my apologies.
I sent you a similar but incorrect directory to your java executable. Use this one instead (I tested it out several times, so it should work):
C:\Program Files (x86)\Java\jdk(JAVA VERSION)\jre\bin\javaw.exe
It is important that you click on the jdk file in your java folder, not the jre file or you wont find the same program. Also make sure it is javaw.exe not java.exe

I did this second way and my computer says "a java exception has occured."when i try to open the file.Please help if you can.
I have the same problem. When i try to open the javaw.exe file nothing happends for some silly reason.
Help me!

The amount of detail for an auto-installer
Yes, but obviously OP is having trouble running the auto installer so I added extra detail to ensure a higher chance that it could be done the first time
I am going to elaborate on what CaptainMurica said,
1) Download the latest optifine version - Ultra D3 for 1.8.3 (As of the time of this post, this is the latest version). It can be found here: http://optifine.net/downloads
2) move it somewhere easy to access, like your desktop.
3) The file should have an icon that is a white box with a cup of coffee in the middle (the java logo). IF NOT, that is ok! Right click on the program, and click open with > Java (TM) Platform SE Binary
If 'Java(TM) Platform SE Binary' does not show up, do this:
1) Right click the file and go to open with> choose a default program > Java TM Platform SE Binary
IF it still does not show up after that step, go to choose a default program again, but instead scroll down to where it says 'Look for another program(or app on win 8) on this PC'. Then navigate to C:\Program Files (x86)\Java\JAVA VERSION HERE\jre\bin\java.exe. Select that program and you should now be able to run the optifine installer.
Once you have found the Java (TM) Platform SE Binary, continue to this step
4) If you have not already selected Java to run the optifine installer, do so now. A popup should appear saying install Optifine (Version) for minecraft.
5) Click install
6) A popup will appear saying that optifine has installed. This does only take a split second, so do not be worried that it was fast.
7) Open up your minecraft launcher, and select the optifine profile
8) Play!
Hope it helped!

It says that the file is unable to open :'c
Right-click it and go to "Open with..." and select the Java runtime. If it gives you the choice, make that the default for JAR files.
And why did you uninstall WinRAR?
