To run Java as an administrator, follow the steps below:
- Press Windows + E key together on the keyboard to open File Explorer.
- Navigate to the Java Installation folder. (The file is usually located at “Windows (C:) > Program Files (×86) > Common Files > Oracle > Java > Javapath.”)
- Once you locate the Java file then right-click on it and select “Run as administrator.”
- Under the User Account Control (UAC) menu, click Yes to proceed further.
2. Verify Java Installation
Another thing you have to do is verify Java Installation on your Windows laptop or PC. It is most important to install the right Java Runtime Environment (JRE) or Java Development Kit (JDK) tool. However, you may address the “Could Not Create the Java Virtual Machine” error on Windows computer if you’ve installed an incorrect program.
Make sure to check the necessary components and verify the installation of the Java program and other tools. Plus, ensure to check the system PATH environment variable to endorse that it includes the right Java directory. To check the Java Installation whether it is correctly placed or not, follow the steps below:
- Click on the Windows Key on the keyboard to launch Start Menu.
- In the Windows search bar, type in “Command Prompt” and select Run as administrator.
3. Under the User Account Control (UAC) menu, click Yes to proceed.
4. Next, type the below command and then click Enter to run it.
java --version
After entering the command, you will see the message on the screen. If you see “Could Not Create the Java Virtual Machine” error, then it means that Java Installation is incorrect. On the other hand, if you see the details about the Java version and its path, it means you’ve installed the correct Java and other programs.
3. Increase System Memory for Java
At certain times, the Lava Virtual Machine launcher shows the error message due to the Java program lacking memory. Generally, the memory allocated to Java is called a Java heap. Luckily, you can solve the Java error message by increasing system memory for Java. Below we have outlined the two most effective steps to increase system memory for Java programs.
Method 1: Increase Java Heap Size by Modifying Variables
- Press the Windows key on the keyboard to launch Start Menu.
- In the Window search bar, type in “Edit the system environment variables” and click Open.
3. Under the Advanced section, click on “Environment Variables…”
4. Under the System variables menu, click on the New button.
5. Enter the below following details in the boxes and then click OK.
- Variable name: -JAVA_OPTIONS
- Variable value: -Xmx512M
Note: The variable value -Xmx512M sets memory available to Java to 512 MB only. However, you can change the value when you need or depending upon the memory.
Method 2: Increase Java Heap Size Using Java Control Panel
- Press the Windows key on the keyboard to launch Start Menu.
- In the Windows search bar, type in “Control Panel” and click Open.
3. Click on Programs.
4. Under the Programs window, click Java from the options. (Now you’ll be directed to the Java Control Panel.)
5. In the Java Control Panel, click the Java button at the top bar and then select the “View…” option.
6. Now, double-click on the “Runtime Parameters” column and type in “-Xmx512m” to assign 512MB Java memory.
7. Lastly, click on OK to save changes and then close the program.
8. You have successfully increased the Java memory.
