How to Fix “No JVM Could be Found” Error on Windows?

The ‘No JVM could be found on your system (Exe4j_Java_Home)’ error typically appears when users attempt to install DbVisualizer, when launching an exe4j executable, or when trying to launch Minecraft—or any other game or application that utilizes the Java environment.

In most cases, this issue arises due to an incompatible Java version. The error is most commonly triggered when users install a Java version with a bit-version opposite to that of DbVisualizer, resulting in the application producing this error.

However, the ‘No JVM could be found on your system (Exe4j_Java_Home)’ error may also be caused by an incorrect Java environment variable setting.

If you’re encountering this issue in connection with an Openfire server, it is likely due to a bug that has been resolved in Java releases newer than Java 8 Update 161.

Note: Refer to our guide on fixing the ‘javac is not recognized’ error.

1. Install a Compatible Version of DbVisualizer

Resolving the issue is usually as simple as installing the correct bit-version of Java that corresponds to the DbVisualizer version you are using.

1. Click here to navigate to the Java website, and under the Windows section, click on the bit version you need to begin the download. Choose Windows Offline or Windows Offline (64-bit) based on your version of DbVisualizer.

   

   Note: ‘Windows Offline’ refers to the 32-bit version among the three available options.

2. After the download finishes, double-click the installer’s executable file and complete the installation by following the on-screen instructions.

   

3. Close the installation wizard and restart your computer once the installation is finished.
4. Upon restart, try the action that previously caused the error and see if the issue has been resolved.

If this method was not applicable or did not fix the issue, proceed to the next potential solution below.

2. Fix the Java Environment Variable

‘No JVM could be found on your system’ error can also result from an incorrect Java environment variable setting.

To resolve the issue, you need to locate your Java installation path and ensure the Java Environment variable points to this exact location. This fix has been confirmed as effective by several users who faced this problem.

1. Navigate to your Java installation directory using File Explorer. By default, you should find it in these locations unless you selected a custom path during installation:

   C:\Program Files\Java\*Java version* - for the 64-bit version
   C:\Program Files (x86)\Java\*Java version* - for the 32-bit version

2. Once in the correct directory, right-click the navigation bar and choose Copy Address from the context menu that appears.

   

3. Copy the Java installation path to your clipboard, then press Windows key + R to open a Run dialog box. Type ‘sysdm.cpl’ and press Enter to access the System Properties window.

   

4. In the System Properties window, select the Advanced tab and then click on Environment Variables.

   

5. In the Environment Variables window, under System variables, select Path and click Edit.

   

6. Look for the environment variable that references Java in the next window. When found, update its value with the correct path you copied in step 2.
7. Restart your computer to see if the problem is fixed upon the next system boot.

Should the issue persist, proceed to the final possible solution below.

3. Reinstall the Current Java Environment

If the problem is related to an Openfire server, it is very likely caused by a bug that has been addressed in more recent Java updates. Oracle has fixed this issue in versions later than Java 8 Update 161.

1. Open a Run dialog box by pressing Windows key + R. Type ‘appwiz.cpl’ and hit Enter to go to the Programs and Features window.

   

2. Scroll through the list of installed programs in the Programs and Features window and locate your Java versions. Right-click each and select Uninstall.

   

3. Follow the same process to uninstall any auxiliary items (Java updates, NodeJs, etc.). To ensure you remove all related installations, click the Publisher column header to sort the entries.
   Note: This makes it easier to identify all Java-related components.
4. Restart your computer after uninstalling all Java installations and associated components.
5. Following the restart, visit this link to download and install the latest Java Runtime Environment (JRE) version. Subsequently, reinstall any other components you previously uninstalled.

   

6. Perform a final restart and check if the issue has been resolved on the next startup.
