I have Java installed on my computer, right now I have the 32-bit but I've tried with every option they currently have. I'm not very tech savvy but I've looked up videos and have gone through the control panel > programs > associate > .jar > set default but when I try to set the .jar files to open through Java or any other option, my only choice is the notepad document.When I type Java into my search bar, it appears at the top and when I hit "run command" it flashes for a millisecond on my screen then immediately closes, I'm not sure if that's supposed to happen or not, but it see

Java .jar file is not downloaded as a java file.

Have you tried the second solution?

"Open the Settings app. Navigate to the System > Default apps.

Scroll all the way down and select Choose default apps by file type.

Locate the .jar file type and choose a default application.

This method offers limited options and you can only choose applications recognized by Windows 10. Fortunately, there’s another method that you can try. To change file associations, do the following:

Press Windows Key + X to open Win + X menu and choose Control Panel from the list.

When Control Panel opens, select Default Programs.

Click on Associate a file type or protocol with a program.

Locate the .jar file on the list and double-click it.

A list of suggested applications will appear. Click on More apps.

Scroll all the way down and choose Look for another app on this PC.

Locate the javaw.exe file. By default, the application should be located in Program Files folder. Select the application and choose it as a default for .jar files.

Optional: Some users recommend changing the parameters of javaw.exe. To do that, simply locate the file and create its shortcut. Right-click it and navigate to the Properties. Now, locate the Target file and add -jar “%1” % . Be sure to select this newly created
shortcut in Step 7.

You can also change file association by right clicking the jar file and choosing Open With > Choose another app. After doing that, follow the steps 5 to 8 from the above"

 

.jar files not working

Hi Mohammed,

JAR (Java ARchive) is a package file format used to aggregate many Java class files into one file for distribution and is built on the
ZIP format. If you are having trouble opening these files, we suggesting reinstalling Java by following these steps:

• Open Settings from the Start menu.
• Select Apps, click on Java, then select
  Uninstall.
• Download and install Java from this link.

Let us know how it goes.

"Reinstall or update Java Runtime Environment

If you can’t run jar files on your Windows 10 PC, you might need to reinstall Java Runtime Environment. To do that, follow these steps:

Press Windows Key + I to open the Settings app.

When the Settings app opens, go to the System section. Now, choose Apps & features from the left pane.

Locate Java from the list and choose the Uninstall option.

After doing that, navigate to Java’s website and download the latest version of the software. Once installed, check if the problem is resolved. Keep in mind that it’s not mandatory that you remove your previous Java installation, so you can skip that step and
just install the latest version on top.

Java will also automatically check for updates, and if updates are available you’ll get a notification. To update Java, simply click the notification and choose the Update option. Now follow the instructions to complete the update"
