  1. How to fix "Could not create Java virtual machine" Minecraft PC/Java


    So, the first thing to do is open the launcher>Installations> and hover over the version and select the 3 dots then click more options.

    now in the textbox replace all the text with this>


    -Xmx4G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -d64


    if you have less than 4gb ram, do:


    -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -d64


    also, install the java runtime environment, minecraft usually comes with its own, but it is very buggy and can lag.

    get the latest here: https://www.java.com/en/download/

    this is all I can say. there are better guides.

    here is one:

  2. error : could not create the java virtual machine

    Hi,

    I realize that you get error message “could not create the java virtual machine” on your PC. I will try to help you with this issue.

    Suggest you to update java virtual machine software and restart the computer to check if that helps.

    Keep us informed to help you further.

    Thank you.

    E61i: Is there a JAVA Virtual Machine

    The E61i *DOES* have a Java Virtual Machine, but like virtually all mobile devices, it is the so called J2ME (Java 2 Micro Edition) Java (also known as MIDP/CLDC).

    Most web sites require J2SE (Java 2 Standard Edition) as is available on PC's (Windows, Mac, Linux). Such J2SE Java "applets" will not work on mobile phones, I'm afraid.

    If you wish to understand the differences in detail, see
    http://java.sun.com/j2me
    vs.

    How to fix "Could not create Java virtual machine" Minecraft PC/Java

    Java

    Hello

    Just a quick question, I have a massive Minecraft Modpack (100+ Mods) and it only runs on Java 7

    I know Java 7 is likely to have security vulnerabilities. Is there any way for me to create a contained Java environment (aside from a virtual machine) in where I can run Java 7 and my Modpack, without the risk of my computer being infected

    Thanks
