  1. I cannot change my default .jar program to java


    I have a windows 10 machine.

    I have run everything fine before I reset my pc.

    My default now is set to notepad, which was my mistake.


    The only options I have to open a file with are apps from the windows store which is not helpful because I need to run this file using Java. Even searching in program files there doesn't seem to be a "java" option.


    yes, I have java installed and it is in my programs on my computer.


    I can add the java installer as a possible app, but this does not work it seems to try to reinstall java and open the file at the same time and causes and error saying it cannot install java again.


    please help


    Thank you.

    :)

    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!

  4. I cannot change my default .jar program to java

    .java to .jar file

    if you know the manual then you know you dont put the code in the program, you convert all of your java class files into a jar file using their compiler.
