Hey guys,

I'm trying to run the new beta 5.0 on my Mac but I get the following error messages when I try to run Rapidminer.jar 
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

    Hi,
    I think, you should install Java 6 before using a Java 6 application :)

    I Installed Snow Leopard and now it works.

    /shrug

    I'm a noob on my mac. I've used PCs my entire life and just switched to mac for my laptop last year.

    Thanks though!
    ;D

    EDIT: And just to clarify, I used the OS X software update prior to my first post and it said my software was updated completely. I also went to the JAVA site and it told me to use OS X software update. Perhaps in the future I will have to manually update?

    I had the same Problem with OSX 10.5.8.
    OSX software update said my software was up to date but Rapidminer Beta 5.0 didn't work.

    I resolved this Issue without installing Snow Leopard.!
    I just changed the order of the Java Version to Java SE 6 64 bit.

    To change this, open /Applications/Utilities/Java Preferences and make sure that a 64-bit version of Java is selected as the default for Java Applications.
    Move "Java SE 6 64bit" up!

    Now it works!! Rapidminer Beta 5.0 looks great!!

    Regards,

    Mike
