    Default Problem running .jar in Windows 7

    Hello everyone, I am new here. I am having a problem running my executable jar file in windows 7. I created a program to open all of my applications from one interface. It runs in windows XP and Vista but not on windows 7. I use Netbeans IDE, built and created the jar file. The manifest file somehow was not edited so i edited it myself.
    I can run the jar file from the command line with java -jar (jar path), but when i double click the jar file i get the following error.

    Could not find main class
    (jar path)
    Program will not exit.

    Has anyone else her every encountered this problem. Does anyone know how I can fix this?

    Unless a mod says otherwise, Id recommend highly that you don't follow the link vudv provided

    Here is the website of software called "jarfix", description seems to suggest it could fix your problem, but no guarantees.
    JarFix/index.html

    -Nothing personal vudv, Just a link to a .rar file with a post count of 1 seems a little suspicious

    The file is only about 22 KB. A little small to be virus infected.
