Windows 10: Trying to download a .jar , when I open it, it says application not found.

I am on windows 10, I havent had problems downloading .jar before, I have the latest java and I am fully updated. Im a bit of a computer noob so any help is great.

:)

 

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"
