Running Minecraft with 64 bit Java

If you have Windows 7 or 8 installed in 64-bit mode, take advantage of running Minecraft on 64-bit Java.

NOTE: Applies to Windows 7 & Windows 8
Why Run 64-bit?

Why run Minecraft with 64-bit Java…


  • Less crashes
  • Smoother and faster rendering
  • Less lagging

Every computer setup is different and every user will have a different experience. But in general, if you have a 64 bit system, then running 64 bit Java will give you a better Minecraft experience.
Checking System

Check if you’re running Windows 7 in 64-bit


  • Click on Start –> Control Panel –> System & Security –> System

You should then have a window that looks something like this…

Checking if your version of Windows 7 is 64 bit

If it says “64-bit Operating System“, then you’re good to go. Scroll down to check your version of Java.

If it doesn’t say “64-bit Operating System” then you’re most likely running 32-bit and you should obviously stick with 32-bit Java. Perhaps have a chat with your local computer shop, brother in-law, kids or whoever it is you turn to when you need to re-install your operating system.

Check if you’re running 32-bit or 64-bit Java


  • Click on Start > Control Panel > Programs > Java
    This should open the Java Control Panel
  • Click on the Java tab –> then on the View button

You should see a window that looks like this…

Java screen indicating 64-bit version

If the ‘Path’ is “C:\Program Files\Java…” then you are running the 64-bit version of Java. Move on to the “Checking Minecraft” tab to see if Minecraft is using the 64-bit version.

If the ‘Path’ is “C:\Program Files (x86)\Java…” then you are running the 32-bit version of Java. Move on to the next tab “Installing 64-bit”.
Installing 64-bit Java

Installing 64-bit version of Java


  • Click on Start –> All Programs –> Internet Explorer (64-bit)
  • Browse to www.java.com
  • Click on the main Download button
    The page that loads should say “64-bit Java for Windows – Internet Explorer
  • Click the button to start the download.
  • Follow the prompts to install 64-bit Java

Once installed, go back to the previous tab and follow the instructions to check that the 64-bit version of Java is installed correctly.

Checking Minecraft

Check that Minecraft is using 64-bit Java


  • Run Minecraft and Login
  • Click on Options –> Video Settings
  • Set the Render Distance to “Far

If a warning appears above the “Done” button, then the 64-bit version of Java isn\’t installed correctly, or you are using a shortcut to start Minecraft which is specifically calling the 32-bit version of Java. Make sure you run Minecraft by using the Minecraft.exe program.

If no warning appears above the “Done” button, then Minecraft is using the 64-bit version of Java.

We hope this has helped you to improve your Minecraft experience, if you have any questions or problems with the instructions here, please feel free to post a comment and we will help you as best as we can.

      Hi jpmc
      Did you definitely run the 64-bit version of Internet Explorer when you went to the Java download site?

    Hi, I wonder if I need a Java for an app (a necessary one) and the Java I use now is in 32-bit, that after I download and install a 64-bit Java, the app would still work. I mean, several years ago when I tried to update my Java, it stopped working and nothing else then complete reinstall of the whole OS didn’t help.

    Thanks in advance for a reply. Bye.

      @DartVader
      Not sure I understand your question. Are you running a 64-bit system? Have you tried to install 64-bit Java and it isn’t working? Please provide more info and we’ll try to help.

  • DartVader

    Ok then :) I’m running a 64-bit system and the current Java is 32-bit. And from the previous experience I am pretty cautious about changing Java (either it was an update, or it would be a different “version”). So I rather asked before installing 64-bit Java. In other words “rather be safe then sorry”.

    Again, thanks for your help.

  • DartVader

    Ok, thank you very much.

  • williamglass

    i have windows vista :(

  • williamglass

  • williamglass

  • modman

    @williamglass
    This *should* do it for you…
    http://www.java.com/en/download/faq/java_win64bit.xml
    Just make sure you are using the 64-bit browser when you go to the link.

    Thx

    I’m having trouble.
    Here’s my trouble.
    So, I’ve had 64-bit Java downloaded already, and I’ve also have been playing the MineCraft for awhile. And I open MineCraft.exe, not the shortcut but the options still says that I am running Java in 64 bit. So I’ve gone through the instructions very closely and re-downloaded Java 64 on the 64 browser and it still says that I’m using 32 bit java.

    • modman

      @FreedomPlanet
      So in the Java control panel, the path is C:\Program Files (x86)\… ?

  • GarredHATES

    can I still install a 64 bit Java with my 32 bit system?

    • modman

      @GarredHATES
      I don’t believe so, pretty sure you need a 64-bit browser for it to give you the option of installing 64-bit when on the Java site.

  • colex

    Trouble….
    The minecraft still said that i’m using the 32 bit.
    the java control panel does not say C:\Program Files (x86)\… anymore, it is C:\Program Files\… alredy, but yet the minecraft still detect 32 bit

    • modman

      @colex
      That’s kinda weird, but then, this is windows.
      I would try this…
      Reboot, install java 64 bit again as per the instructions again, then reboot again, then check it in Minecraft. If still no, then do a fresh install of Minecraft.
