    I made an app that runs ok in win7, with 32 bits, but can't run in win8 64 bits, any clue?

    Run the jar from the command line to see the full error message: java -jar <your jar>

    "could not find or load main class ... (path of jar)"

    It is not related to 32 bit vs 64 bit. It is better to post the full error message as it might include more information.

    Check the output of java -version. Maybe you need Java 8 (if the app was compiled with Java 8).
