Program will exit.-I tried allocating more memory to the java virtua

    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!

    Executable Jar files

    Hi Pankaj,

    Perhaps an updated version of the program was released. We suggest reinstalling the program, and check if it helps.
