If you are having issues with .jar files not working on your PC, Jarfix is a great way to fix it. With Jarfix, you can take existing .jar files on your PC and link them back to Java. This will, in turn, allow you to easily open and use .jar files by double-clicking them instead of having to use other workarounds. On top of this, after you run the Jarfix, all of the .jar files on your PC will get the Java logo and look how .jar files are supposed to. So, without any more delay, here is how to use Jarfix to repair .jar files on your PC.
What we'll cover in this Jarfix guide:
Download & Install Java
Step 1) Downloading Java
Before you can run the Jarfix, you need to make sure that you have the correct version of Java. We have a complete Java guide that you can check, but we will go over the basics here.
First, access the Java download page. On this page, click the version of Java you want and select ‘Windows'. Click the link next to ‘x64 Installer', and the download will start after a few seconds.
Step 2) Installing Java
With Java downloaded, we can now install it. This is just like any other Windows program. Double-click on the .exe file you downloaded. The Java installer will open. Click next a few times, and Java will begin installing. After a few minutes, the installation will finish. Click the close button, and Java will be installed!

How To Use Jarfix
Step 1) Running Jarfix
Now that you have Jarfix downloaded, we can run it. This is what actually fixes your .jar files and links them back to Java.
To do this, just double-click on the jarfix.exe file you download. This will open and automatically run the Jarfix program.
Once it is complete, a pop-up will come up that says “The .jar suffix (Java Archive) has been registered successfully. Jar packaged Java applications can be executed again by a double-click”.
This means that .jar files your computer have now been completely fixed, and you no longer will have any issues opening up .jar files.
Step 2) Confirming Jarfix Has Worked
After you have ran Jarfix, you can check to make sure that it worked by double-clicking on the .jar file you are trying to open. It should open right away.
You will also notice that if your icons weren't Java icons and instead .zip files, WinRAR files, or anything else, this will no longer be the case. They will now display a Java logo.

Is Jarfix required to open .jar files?
No, all you need to open .jar files is Java. Jarfix will like your .jar files to Java once you have Java installed.
Will Jarfix change the icons on .jar files to the Java logo?
Yes, Jarfix forces Java to start handling .jar files on your computer again. Sometimes, programs like WinRAR, VSCode, or other apps will take over opening .jar files. This isn't ideal, and it can be very annoying when you are trying to open a Java app.
However, when these programs take over your .jar files, the icon on those files changes as well. When you run the Jarfix and link your Java files back to Java, the icons will start displaying the Java logo again showing they are associated with the correct program and can be double-clicked to open.
