    Hi,

    Step 1: Try Restarting the Application, if this does not work try step 2

    Step 2: Switch off the Anti Virus on your computer and Try reinstalling the extension again. 

     

    Make sure you have the updated JAVA Version.

    Are you able to successfully install other extensions?

    Also, remember that the Weka extension isn't just one operator called "Weka" but rather it is a set of modeling extensions using algorithms from the open-source Weka project.  If you look in your extensions folder in your operator list, it actually looks like this:
