I have a 32-bit computer and I downloaded Minecraft and tried to play the demo. But when I started it, it said something like 'Error: could not initialize jvm 64' or something. So does that mean Minecraft can be played on only 64-bit? I really want to play Minecraft. Is there a 32-bit version or something?

    Question is OK, but a new user named "Programming coder" asking about something like this... makes me wonder.

    Can you tell us what kind of computer and OS you actually have? (“32-bit computer” doesn't tell us enough.) Also, what version(s) of Java do you have installed?

    @Rudolf L. Jelinek And besides, minecraft was created by programmers wasn't it? :).

    @Kaizerwolf Oh, that's right, it bundles its own JVM now. Nevermind! :)

    @Programmingcoder We're still trying to gather all the details necessary to understand what's actually on your computer, what steps you've done, what the error is, etc. Editing your question to include more details, and maybe the step-by-step way that you can reproducibly cause the error (and a more exact quote of the error, or screenshots) would help. When answers start being given, they won't be in these tiny comment boxes, they'll be below, and look more like the question post in size and layout.

Try reinstalling Java, and make sure that you have the 32x version installed. If this does not work, try opening the Minecraft launcher. Click "edit profile" on the lower part of the launcher window. Another window should pop up. In this window, check the box labeled "JVM Arguments." Where it says -Xmx(Number)G. Replace (number) with half of the number of gigabytes of RAM. If it is already so, or greater, increase it. If this does not work, try downloading this minecraft launcher version, and completing the JVM Argument step again.

  • But the JVM runtime folder is provided with minecraft. I have already tried reinstalling java (32-bit) many times.

The reason why it was not working was that the java included with minecraft was 64-bit. I replaced the file in ProgramFiles > Minecraft > runtime > java x64 > 1.8.0 with the java files on my computer.
