Tips For Resolving The Error

Follow the most easiest and suitable tip according to your comfort.

Computer Memory Cleaning

Insufficient memory in your COMPUTER is one of the most common causes of Java Virtual Machine launcher difficulties. This could be a problem with your computer’s total RAM or the amount of memory you assign to the Java Runtime. To address the former, simply delete all of the apps you don’t use, and your computer will be clutter-free (and presumably problem-free).

The error “Error Message: Could not create the Java Virtual Machine” appears when Java allocates inadequate memory space. This is one of the most typical Java Virtual Machine Launcher issues you’ll come across when playing Java games like Minecraft.

Go to the Control Panel’s Systems settings and enter the Advanced options window to fix the memory space assigned to Java. A ‘System Variables’ option can be found by clicking on the Environment Variables option. Select the ‘New’ variable option and give the variable the name ‘_JAVA OPTIONS’ with the value ‘Xmx512M.’ (The greatest space you can allot to Java is Xmx, and the least space you may allocate to Java is Xms.) This will solve Java virtual machine launcher errors.
