  1. .jar Files Open in Internet Explorer Instead of Running


    I think this is a pretty common problem, but I'm wondering if anyone has found a solution.


    I need to run a .jar file, which I would normally do by double-clicking on it. However, the file now just opens in Internet Explorer, which tries to download it again.


    Does anyone know how to run a .jar file instead of opening it?

    :)

    Hi Robert,

    Welcome to Microsoft Community.

    I understand that .jar files opens in Internet Explorer by default and downloads again on Windows 10. I will certainly help you.

    I suggest you to follow the below steps and check if it resolves the issue.

    1. Right click on the .jar file, select Open with
    and click on Choose another app.

    2. Select the app you want to open the .jar file from list.

    3. If required, highlight the app and check the option
    Always use this app to open, click OK.

    I have the same problem, I accidentaly switched a .jar file to open with internet explorer, or notepad, I can't remember, and I forgot to unselect set it to the default, and now I can't get back to the java thing, please help.

    Jar file opens with internet explorer

    Your .jar file-association has probably been hijacked, perhaps by Internet Explorer.

    You can fix the problem with:

    • Download and run the free
      Jarfix, or
    • Uninstalling an then re-installing Java Runtime, or
    • In Windows Explorer, right-click on the .jar file, select Open with
      and click on Choose another app. Navigate to and select javaw.exe.
      You would need to ensure a -jar parameter is added.

    It would be better to add the JRE executable folder to the PATH environment variable,
    although not absolutely required.
