Minecraft has a special place in every true gamer’s heart, but most would agree that the game is far from problem-free.

Although Minecraft users encounter a few bugs and errors here and there while playing, some of the problems happen outside of the game as well, or in this case, while attempting to launch it.

In this guide, we’ll talk about the infamous “Error occurred during initialization of VM” problem, and the good news is that we know exactly how to fix it.

Here’s what you need to know.

The Problem Explained

Users reported seeing this issue right after starting Minecraft through the launcher, as usual. The problem consists of the game not starting, and the user is presented with the following message: “Error occurred during initialization of VM”, as shown in the image below.

Then, the program exists and the game doesn’t launch, which leaves users confused and sometimes even concerned, as the last sentence in the error prompt mentions a fatal exception followed by immediate termination of the program.

Fortunately, this error isn’t as serious as it sounds, and the reason it happens is that the Virtual Machine doesn’t have enough memory allocated for it to properly start, and changing that is not a difficult process.

We know precisely how to solve this problem, and you will too after reading the content in the sections below.

Let’s get right into it.

Fix 1: Ensure You Have The Right Java Version Installed

One of the most common fixes for the Minecraft “Error occurred during Initialization of Virtual Machine” issue is to ensure you are running the right Java version for your system.

This idea has been proposed in a well-liked Stack Overflow discussion about the issue, as well as in a couple of other locations, like this Reddit discussion.

The issue here is that you may have a 64-bit operating system yet have the 32-bit Java installed on your PC, and the best way to solve that is by installing the correct Java version.

However, prior to delving into that, we propose verifying the aforementioned statement, and you can achieve this by following the steps below:

1. Press Windows + E on your keyboard at the same time. This will open the Windows File Explorer.
2. Right-click anywhere in an empty area and choose Properties from the list of options.
3. Look for the information listed under the System category to see if your operating system is 32-bit or 64-bit, as shown in the image below.

If it’s 64-bit, which is most likely the case, you need to make sure you also have the right Java version installed, which is also the 64-bit one.

To do that, you first need to uninstall your current Java version from your system and ensure there are no leftover files.

This is what a Reddit user commented on a thread made by another user who faced the same Minecraft error due to having the wrong Java version installed on their PC.

You can remove your existing Java version through the Apps & Features section in Windows 10. Here’s what the process looks like step-by-step.

1. Press Windows + S simultaneously on your keyboard to open the search box. In it, type Apps & Features, and then press Enter on your keyboard to initiate the search.
2. Within the Apps & Features panel, search for Java, click on it, and choose Uninstall.
3. When the process is complete, open the Program Files folder on your computer (which is by default located on your C Drive) and search for the Java folder. Manually delete it by right-clicking it and choosing Delete.
4. Although not always mandatory, we recommend restarting your computer after the uninstall.

Now that you’ve successfully uninstalled Java from your computer, it’s time to re-download the correct version for your OS type from the official Java website.

Once you install the 64-bit version of Java, we recommend rebooting your PC once again. When it’s finally back up and running, launch Minecraft and see if the error persists.

For many users, this method solved the problem, given there weren’t any other issues, such as the one where the VM doesn’t get enough allocated memory for it to run properly. We cover that in the next section below, so make sure to check it out if the problem is still not fixed.

Fix 2: Allocate More Ram To The Java Virtual Machine

Another very common fix for this problem is allocating more memory to the Java Virtual Machine. Although it sounds like a daunting task at first, it’s not that difficult to do, and we’ll show you exactly what steps you need to take.

Let’s have a glance.

1. Press Windows + R on your keyboard to open the Windows Run panel.
2. In it, type in sysdm.cpl and press Enter on your keyboard, as shown in the image below.

3. In the window that opened, click Advanced at the top.

4. Click Environment Variables at the bottom-right corner of the window.

5. Under the System Variables section, click on New, as shown in the image below.

6. Within the “Variable name” field, type in “_JAVA_OPTIONS” and in the “Variable value” field, type in “-XmX512M”, then finish by clicking the OK button at the bottom. This means that you’ve just successfully allocated 512MB of RAM to Java. You can increase this number to 1024M or more.

You can also take a look at this helpful video tutorial that covers the entire process from beginning to end if the text-based explanation is not clear enough.

Note: You can also use the short command (such as “-mx512m) if you see no success with the one listed in step #6, as some users reported that it made a difference for them, although they’re the same commands, just one shorter than the other.

Note: You can allocate more memory to the Java Virtual Machine than we did in the example above, but be careful as some users reported that a very high number can also cause it not to work, especially with the 32-bit version of Java.

Now that you’ve successfully allocated more memory to your Java Virtual Machine, the problem should no longer be there when you’re trying to launch the game.

Conclusion

Now you know more about the VM Minecraft error and how to allocate more RAM to the Java Virtual Machine, which should be enough to fix the issue with Minecraft not launching for good.

The methods listed in the guide above helped many users, and hopefully, they’ll help you too and ensure you have a non-interrupted gameplay experience.

Today, we will find out why we are getting the error that occurred during the initialization of VM in Minecraft and how we can resolve it. So, let’s start by understanding the error and the possible reasons.

Describe Error and Its Causes

We want to make a Minecraft server, but we got the following error using our 64-bit computer. The error states as follows:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine
Error: A fatal exception has occurred. The program will exit.

We found that environmental variables like CLASS and CLASSPATH would help, so we tried those, but we still got the above error. What is this error saying, and how to eradicate it?

Minecraft lovers are allowed to do various things. However, the one who tries to create their server and perform different things inside the game may face an error described as Error occurred during initialization of VM.

It is one of the most common issues faced by Minecraft players. Usually, it happens when they are trying this game for the first time on their machine.

However, it is not a repetitive problem, and we can easily fix this kind of error. Let’s find out the possible reasons for this error.

1. We may have an incorrect version of Java, which means our Java version is incompatible with our machine.
2. We may have allocated the wrong amount of RAM, or we are trying to allocate more RAM than our system allows us to allocate.

Resolve the Error occurred during initialization of VM in Minecraft

There are different ways to fix this issue; we can try any of them based on our situation and the machine’s specifications.

1. The first solution is to uninstall Java completely from our device and reinstall it again. Make sure that we have the right version of Java.

   For instance, we need to select Java, either 32-bit or 64-bit, based on what Windows version and machine architecture we have.

2. Allocate the correct amount of RAM. It is essential regardless of what game we are playing.

Remember, allocating less RAM will not let us play a game properly. While allocating more RAM will result in an error.

To allocate the right amount of RAM, open the startup script and update the values of the `-Xmx/-Xms` arguments.

Make sure that we have allocated the RAM that our machine can easily and safely handle. Otherwise, we will be facing various issues here and there.
