How to fix “Could not create the Java virtual machine”

Java remains a popular programming language to this day. It may be old but has not lost its user base or usefulness over the years. It is still used by many developers and is in active development. Changes and improvements to the language are made all the time which makes editing and running Java-based applications very easy.

Java virtual machine error

Fix was unable to create the Java virtual machine

An error “Could not create a valid Java tool” usually occurs when compiling code in an IDE. The error is not descriptive enough to point users to the real problem however, it is usually the result;

  • Wrong Java version used
  • Wrong SDK version installed
  • Incorrect environmental variables established
  • Errors when verifying the version of Java to be used
  • Missing libraries in the IDE
  • Errors in memory management

The solution will vary depending on the root cause. Try the following.

1. Check for a compatible Java version

The Java virtualization tool usually does not appear to be created when code is compiled in an IDE. This happens because the IDE is not compatible with the version of Java installed on your system.

Check the versions of Java that your IDE supports. Next, check what version of Java is installed, and make sure it is compatible with the supported version. If not, install the correct version.

2. Look for environmental variables

The Java parameters set in the Environment variables on Windows 10 can cause us to be unable to create a valid Java tool error.

  1. Open File Explorer.
  2. Enter this explorer shell:::{BB06C0E4-D293-4f75-8A90-CB05B6477EEE} in the location bar and tap Enter.
  3. Click Advanced system settings in the left-hand panel.
  4. Go to Advanced Tab.
  5. Choose Environmental variables and click New under System Variables.
  6. Enter _JAVA_OPTIONS in the name field.
  7. In the way / value, insert: -Xmx1024M
  8. Click OK.
  9. Restart the app.

Additionally, you should make sure that the correct path for the Java SDK is provided.

  1. Open File Explorer and go to C: Program Files Java
  2. Open the folder for the JDK version you want to use.
  3. Copy the path to the folder.
  4. Open environment variables (see previous steps).
  5. Fo System Variables, select JAVA_HOME.
  6. Click Edit.
  7. Go into the path that you have copied and click OK.

3. Look at starting arguments

Refer to the initial arguments set. You may have the correct version of Java installed but the initial arguments on the version to be used may need to be compiled into something else. If you did and updated in Java, it is very likely that the initialization arguments still refer to the older version.

4. Check consensus

For any arguments you enter, make sure the concurrence is correct. The slightest error can lead to a Java device error. Look for additional hyphens or incorrectly named versions.

5. Reset Java

Try resetting Java. It could solve problems you have when opening an IDE or similar app.

  1. Open Control Panel.
  2. go to Programs> Enter a program.
  3. look for Java and select it.
  4. Click on the Uninstalled button at the top.
  5. Allow Java to uninstall.
  6. Download and reinstall Java from here.

6. Check memory allocation

One of the main reasons is that we could not create a valid Java engine error if not enough memory is allocated for its use.

  1. Open File Explorer.
  2. go to C:Program FilesJava
  3. Open the JDK folder with the currently installed version number.
  4. Look for a file called jvisualvm.exe and run it.
  5. The app provides a GUI for memory management.
  6. Increase the amount of memory and try again.


Establishing a development environment can take a long time. There are many components that need to be established and requirements that must be met before you can develop or compile code. These errors are not unique to Java because each language has its own set of requirements that must be met in order to use them.
