A programming language like Java is more than just a way to write programs; game and app developers use it too. However, it’s very common to experience Java crashes. If you are having trouble when trying to launch an application that is built around Java, then this guide will help you fix the problem.

Not all Java virtual machine errors are the same. They can occur for many different reasons. In this article, we will explain the most common causes of Java virtual machine launcher error – Could not create the Java Virtual Machine and how to fix it.

What is Java in simple words?

Java is a popular programming language that can run on a variety of different operating systems and devices. It has many different uses, including in web development, mobile applications, desktop applications, and server-side programming. Java generates a virtual machine (VM) that executes the code written in Java. A Java virtual machine launcher error can occur if something goes wrong with the data or code that’s being processed by the Java virtual machine.

What is a Java virtual machine error?

A Java virtual machine error, also known as a JVM error, is classified as an error generated by the Java Virtual Machine. When this type of error occurs, it usually means that the computer cannot read or understand the code. This can happen for a number of reasons, such as when the computer isn’t updated with required patches or if it’s not compatible with Java. If you come across a JVM error while using your computer, it’s important to know how to recover from this problem. Here are some steps to take in order to fix this issue and continue using your computer.

Данная публикация посвящается всем ценителям Minecraft и других игр, требующих установки Java. На днях знакомые попросили помочь: при попытке запустить Майнкрафт у них появлялось сообщение — Java Virtual Machine Launcher ошибка, как исправить сейчас расскажу.

Не хватает памяти

При установке Джавы, необходимой для работы некоторых игр, отображалось следующее окно:

Она указывает на то, что для создаваемой виртуальной машины не хватает памяти. Очень часто подобная ситуация возникает, если некорректно выходить из игры (нажав Alt + F4 ) или при внезапном отключении ПК.

В моем случае, ошибка появилась после того, как пользователь случайно удалил компонент Java, потом пытался его переустановить, но на последнем этапе инсталляции отображалось вышеупомянутое окно.

На зарубежных источниках нашел два решения. Начну с более простого.

Настройка переменной среды

• Открываем панель управления. В Windows 7 это можно сделать через меню «Пуск», в «десятке» достаточно кликнуть правой кнопкой мышки по кнопке «Старт» (или нажать Win + X ), и выбрать из списка нужный элемент:

• Переходим к разделу «Система»:

• Слева кликаем по ссылке «Дополнительные параметры…»:

• В новом окне снизу есть кнопка «Переменные среды», которую стоит нажать:

• Кликаем по кнопке «Создать…», присваиваем новой переменной:

имя «_JAVA_OPTIONS»

значение «-Xmx512M»

• Обязательно сохраняем все изменения, нажав на ОК. Перезагрузка компьютера не требуется.

Теперь при запуске установщика Джава ошибка Java Virtual Machine Launcher не появиться.

Переходим ко второму способу.

Создание файла запуска

Покажу всё на примере Minecraft.

• Открываем пользовательскую папку, где хранятся игровые настройки. Для этого нажимаем Win + R и пишем команду:

%appdata%

• На экране отобразится каталог, в котором нужно найти игровую директорию, войти в неё и внутри создать новый текстовый документ (Блокнот):

• Туда стоит записать следующую фразу:

java -Xms650m -jar "c:\Users\USER_NAME\AppData\Roaming\.minecraft\minecraft.exe

Вместо USER_NAME пишем название своего аккаунта. Оно указано в адресной строке окна. Учетная запись не должна содержать русских символов. Только латинские (английские), иначе способ не сработает.

• Теперь нажимаем на пункт меню «Файл», затем выбираем «Сохранить как». Указываем имя «minecraft.bat» и указываем тип «Все…», как показано на скриншоте:

• Осталось только создать ярлык для созданного элемента и отправить его на рабочий стол, чтобы через него запускать игру.

Java is a versatile, machine-independent programming language that is used to write a variety of different applications. Unlike most other applications, you can run java applications equally well in Windows, Mac, or Linux, provided you have installed Java Virtual Machine (JVM) in your system. However, if JVM breaks, then none of your java applications run.

One recent impact having a broken JVM launcher was felt by users of Minecraft. A recent update brought new features, but also required Java 16 to set up a server. Those with older version of JVM were greeted with a Java Native Interface (JNI) error.

There are other examples where a malfunctioning JVM launcher caused an application to not work, and it could probably happen again in the future. We have this article prepared, so that you can be prepared when your JVM launcher has an error.

What Causes Java Virtual Machine Launcher Errors

You can somewhat diagnose what is wrong with your JVM and attempt a corresponding fix based upon the type of error message that you see when you JVM does not work.

Reinstall/Update Java

If the error message you see is “Java Virtual Machine Launcher Could Not Find The Main Class,” then Java has been incorrectly installed or Java installation has been corrupted in your machine.

JNI errors can be caused by outdated version of Java.

To fix this, you need to reinstall Java Runtime Environment.

Windows 10

1. Launch Settings (Press Win + I), then navigate to Apps.
2. Scroll to find Java and select Uninstall.
3. Download and install the latest version of Java.
4. Restart your computer.

Windows 11

1. Launch Settings, navigate to Apps > Apps & features.
2. Scroll to find Java.
3. Click on the kebab button to its right, then select Uninstall.
4. Download and install the latest version of Java.
5. Restart the computer.

Increase System Memory for Java

You will get a “Could not create the Java virtual machine” error if Java is trying to use more memory than has been assigned to it.

You can fix this by increasing the amount of memory allotted to Java.

Note: The variable value -Xmx512M sets memory available to Java to 512 MB. You can change this value depending upon how much memory your Java was utilizing before. For instance, setting this to -Xmx1024M assigns 1024 MB system memory to Java.

Run as Administrator

Sometimes JVM errors can occur because you do not have sufficient user privilege to run the application.

You can fix this by configuring Java to run as administrator.

1. Press Win + E to launch Windows Explorer, then navigate to Java installation folder. (Usually located at “…/Program Files(x86)/Common Files/Oracle/Java/javapath”)
2. Find java.exe and right-click on it.
3. Select Properties.
4. Switch to Compatibility tab and put a tick mark on Run this program as an administrator.
   
5. Click Apply, then click OK.

Set File Type Association to Java

If your error message is “Unable to access Jar file,” then one of the reasons for this issue is that your jar file association is not set to Java.

Windows 10

1. Launch Settings (Press Win + I)
2. Navigate to Apps > Default apps.
3. Click on Default apps by file type.
4. Scroll to find .jar from the list of file types.
5. Click on the currently set default application next to it.
6. Click on Java(TM) Platform SE binary.
   
7. Close Default apps setting.

If you’re here, you probably tried opening a Java application on your system, and you got an error message like “Java virtual machine launcher error,” and you’re looking for how to get rid of the error.

You’ve come to the right place. In this article, I’ll explain 3 tips you can use to fix the error in the easy-to-follow steps below. Even the most casual system user can follow the steps, so they aren’t too technical.

Why/How Does The Error Occur?

Before I dive into the tips, it might be important for you to know a little bit about how and why the error occurs. 

This could help in preventing the error from occurring. 

Administrator Access Issues –

Sometimes this error occurs when you try to open a Java app like Minecraft because you haven’t enabled Java to run as an administrator.

In this case, the fix is usually very easy to carry out. All you will need to do is make Java run as an administrator, and your Java apps should normally work again without the error occurring again. 

Issues With Your Java Installation –

Since the Java Virtual Machine is used to run Java programs, if there are issues with its installation, it could lead to errors like the “Java virtual machine launcher error.”

The fix is straightforward too. You will just need to reinstall it. Also, always download Java programs from their official sources to limit the chances of the error occurring.

Allocated RAM (Random Access Memory) Issues –

Errors can occur when the Java Virtual Machine needs more RAM than its current allocation. 

Fixing this is easy too. You can increase the allocation. Also, ensure you keep your system uncluttered so as not to slow it down or cause errors. 

These causes are just the likely options; sometimes, the error can occur unforced. 

Here are the tips that will help get rid of the error. 

You can use any of the tips below. If one doesn’t work, go to the other until the error resolves. 

Please Note This Warning: Don’t skip any of the steps below to ensure its efficiency. 

1. Allowing Java To Run With Administrator Access

The whole idea of this tip is to select the Run As Administrator option for Java. This helps fix the error if it occurs because of Java’s lack of access.

How To Run As an Administrator

The first thing you have to do is use the (Windows + Q) shortkeys to open Cortana.

Use the search box to search for Java. Do that by inputting Java and clicking on entering.

When the search results come back, right-click on Java to open up some options.

Search for and click on Open File Location in the list of options that appear. 

Note: You’ll see the option to “run as administrator”. Don’t click on that. It won’t permanently help you. Just continue the steps below.

This will immediately open Java’s file in your File Explorer.

You’ll see the Java .exe file. Right-click on that file, too, and in the list of options that appear, click on Properties. 

You’ll be taken to a menu with a lot of tabs. Look for and click on the Compatibility tab. 

Go to the Settings section of the Compatibility tab and click on the box to the left of the Run This Program As An Administrator option in that section. 

Once the box is checked, go down a bit and click on Apply to ensure your changes will be in effect.

After that, click on OK to confirm all of the changes and then exit the menu. 

This should help get rid of the “Java virtual machine launcher error,” and your Java programs should be back to working normally without any issues at all.

2. Uninstalling And Reinstalling Java

This tip is useful when the issue is from your Java Installation. 

There is a guide below that could help you to know exactly where the issue stems from. But you could just do it the old-fashioned way and use the first tip, and if it doesn’t work, you could try the next one out. 

The idea is to uninstall Java, find the latest official version, and reinstall that. This should help clear any issues ranging from bugs in the cache to faulty installation settings that could be causing the error to occur.

How To Uninstall And Reinstall

You’ll have first to use the Run window. Open the Run window by using the shortcut keys (Windows + R).

Input this – appwiz.cpl in the Run window and click on Enter. 

You’ll then be taken to the Uninstall Or Change A Program menu.

Here’s where you’ll be able to uninstall Java.

You can use the search box on the menu to search for Java, or you can scroll down to search for it. 

When you do find it, click on it. You should see the option of Uninstalling appear. Click the Uninstall option. 

Follow through with the Uninstallation process using the onscreen instructions.

When you’re done with the Uninstallation process, reboot your system. Then start the reinstallation process below.

Reinstallation

Follow this link if you don’t already have the official Java download page. 

When you click the link above, the download page should appear. 

You’ll be given options for downloading. 

• 32-bit Java
• 64-bit Java

You should download both options if you don’t know which one you need. 

You can also download both options if you use 32-bit Java browsers and 64-bit browsers.

Remember to download the Offline option. 

When you’re done downloading the file, open it, and follow the installation process (the Java setup wizard) to install it. 

When you’re done, your Java programs should be running smoothly back again without the “Java virtual machine launcher error occurring.

3. Setting Up For Java A New System Variable

This tip addresses the RAM issue. What this tip does is it allows users the option to expand the allocated RAM for Java. 

This allows Java the much-needed bigger global maximum heap memory size. 

How To Set Up A New System Variable

You’ll have first to use the Run window. Open the Run window using the shortcut keys (Windows + R).

Input this text – sysdm.cpl into the Run window and click on Enter. 

This should open the System Properties menu.

In the System Properties menu, you will see quite a lot of tabs. Locate the Advanced tab and click on it to open its menu.

In the Advanced tab, go down a bit and click on the Environment Variables… option. 

When a menu appears, you’ll first see two sections. Go to the second section (System Variables).

Select the New option in that section. You’ll be asked to create a new system variable. Follow exactly the steps to ensure this tip works out for you.

• Variable Name –    _JAVA_OPTIONS
• Variable Value –    –Xmx512M

What the above new system variable does is that it increases Java’s allocated RAM to 512 MB. 

This should be enough to ensure it works properly and the “Java virtual machine launcher error” stops occurring. 

Please input the variable name and value exactly as seen above.
