    Cannot Open .jar files

    I've been facing an issue on my Windows 11 system related to .jar files. Despite using the Jarfix tool, I'm still unable to open .jar files on my system.

    Here are some details:

    • Operating System: Windows 11
    • Tool Used: Jarfix
    I've utilized Jarfix to fix the file association for .jar files, but the problem persists. When I try to open a .jar file, nothing happens. No error messages or prompts.

    Has anyone encountered a similar issue on Windows 11, and if so, how did you resolve it? I would greatly appreciate any tips, or suggestions to get .jar files working smoothly on my system.

    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!
