Java is a computing platform that allows you to play games and view videos on your computer. You can tell that your computer is having problems with Java if you see Java errors appear when you try to run a program or visit a website that is based on Javascript (the programming language used for Java applications). The most reliable way to fix Java problems is usually to reinstall Java on your computer, although there are also many other methods and tools available for repairing Java.

Steps

Reinstalling Java

Access the Control Panel through the Start menu located at the bottom-left of your screen.

Double-click on "Add/Remove Programs."

Scroll down until you find Java in the programs list. Select the Java program and press the "Remove" button to remove it from your computer. Wait for Java to be completely removed (you will see it disappear from the programs list once the process is complete).

Download the newest version of the Java software for free from the Java website. Follow the steps provided during the installation process until Java has been reinstalled successfully.

Other Methods for Repairing Java

Consider using other methods to fix Java if you don't want to completely remove the version that you already have installed. There are many tools available such as Microsoft Windows Installer Cleanup Utility and Uniblue Registry Booster that can detect Java errors and repair them.

Make sure you don't have any software installed on your computer that is blocking Java from running properly. Some antivirus programs may misinterpret Java as a software that is threatening your system's security and consequently you will see a message saying that Java was not found.

Use the correct version of Java that matches the software that you are trying to run. You will not be able to run programs that require Java if the version of Java that you have installed on your computer is incompatible with the program that you wish to open. You can try to change the settings on other programs to make them compatible with Java or upgrade or downgrade your Java version.

Consider reinstalling your operating system if other attempts to repair Java fail. You will have to format your hard drive, which will consequently delete all previous data stored on your computer including Java. You should then be able to install Java correctly from scratch after the operating system has been reinstalled.
