Windows 10: Opening a JAR file in Windows 10?

    Opening a JAR file in Windows 10?


    Hi, hope I am posting this to the right forum section.

    I have this JAR file downloaded and of course, it needs Java in order to open it.
    In Windows 10, is there any way to find out if I have Java installed?
    Or, can Windows 10 open up JAR files natively?

    If not, then how can I know if I have Java installed on Windows 10?
    In Windows 7, it was easier to know.

    Thanks

    If you did an upgrade,chances are high that you would have Java installed.Control Panel>Java would confirm you this.
    Isn't the JAR file opening?

    java installed


    I would say look in folder c:\program files or c:\program files (x86); if you find an folder Java\jre xxx\bin with java.exe in it you have Java installed.

    I had this exact same problem. A few web searches produced a program that re-associates .jar with Java Runtime. If you are certain that it is installed try this program:
    Link: http://johann.loefflmann.net/downloads/jarfix.exe
    Original Website: Jarfix

    This worked for me and I hope it works for you!

    It's even easier than that to check for Jave: Open control panel - has an entry if installed.

    From it's CP you can update and after that it should associate.

    Windows cannot natively open jar files.
