Step by Step Tutorial on How to Open a JAR File in Windows 10

In this section, you’ll learn how to open a JAR file in Windows 10 by following some easy-to-understand steps. Each step will guide you closer to successfully accessing your JAR file.

Step 1: Install Java

First, make sure you have Java installed on your computer.

Java is essential for running JAR files. You can download it from the official Java website. Make sure you get the latest version to avoid compatibility issues.

Step 2: Set Java as the Default Program

Next, set Java as the default program for opening JAR files.

Navigate to the JAR file you want to open, right-click it, and choose "Open with." Select "Choose another app," find Java, and check the box that says "Always use this app to open .jar files."

Step 3: Navigate to the JAR File

Use File Explorer to find the JAR file you wish to open.

Being familiar with where your file is located will save you time. If you can’t find it, use the search bar at the top-right corner of File Explorer.

Step 4: Run the JAR File

Double-click the JAR file to run it.

If everything was set up correctly, the file should now open with Java. If it doesn’t, repeat the earlier steps to ensure Java is the default program.

Step 5: Troubleshoot if Necessary

If the file doesn’t open, you may need to troubleshoot.

Check if your Java installation is up to date. Sometimes, older versions can cause issues. Also, ensure the JAR file is not corrupted by trying to open a different JAR file.

After completing these steps, your JAR file should open, allowing you to run the Java application inside it.
