    Been Struggling To Get Executable Jar's To Open.


    I'm on a computer that had some messed up java settings from a past user. Can't open executable jar's by double clicking. Tried so much shit so long ago that i've forgot what I did. I gave up. Now as the months passed by I really need to use this laptop for a running a bot client, which of course uses java to launch.

    I completely wiped the instalation folders of java jre/jdk, and just installed JRE (oracle chose x86 installation when I have a 64 bit system, but that shouldn't be a problem right?). I think I have the enviromental variables right now, but I a not completely sure.

    Here are User Variables:


    JRE_HOME:
    C:\Program Files (x86)\Java\jre1.8.0_181

    Path:
    %USERPROFILE%\AppData\Local\Microsoft\WindowsApps;C:\Program Files (x86)\Java\jre1.8.0_181\bin
    %USERPROFILE%\AppData\Local\Microsoft\WindowsApps
    C:\Program Files\Microsoft VS Code\bin

    System Variables
    Path:
    C:\Windows\System32
    C:\Windows
    C:\Windows\System32\wbem
    C:\Windows\System32\WindowsPowerShell\v1.0\
    C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static
    C:\Program Files (x86)\GnuPG\bin
    C:\Program Files (x86)\GNU\GnuPG\pub

    ---

    So with my first problem, do I have any of the environmental variables set wrong? I know they were before. But Now that I think I have them right I still can't open them by clicking due to the default program being wrong.

    I get the message:

    ---
    How do you want to open this .jar file?

    Keep using this app: "C:\Program Files\Java\jdk-9.0.1\bin\javaw.exe" -jar "%1" %*

    Other options
    ---

    Now when I do click more apps there two "Java(TM) Platform Se Binary"'s. Sweet. Try them both none works. The first one opens a command and dissapears very quickly, and then goes away, the second one does nothing at all. Alright I gotta find a way to change the default program manually...

    Alright go to "Control Panel\All Control Panel Items\Default Programs", and click on "Associate a file type or protocol with a program". Then click "choose default apps by file type". Scroll down a long list to find ".jar". Wohoo right? nope.

    Pops up an error message saying that there is not a default app to open this file type. WELL NO ****ING SHIT. How in the hell do I actually make it to where it can launch with a double click? Sorry for the long post but I have to go in detail about every little thing since it may be needed.

    :)

    jar files

    Fixing .jar file opening on Windows requires two steps:

    • Open the Control Panel, and chose "Default Programs - Associate a File type or protocol with a program". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)".
      A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
    • Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. This is normally: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

    I Hope this Answers your Question!

    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.
