The Visual Programmer software has been updated to enable you to choose the directory where your Visual Programmer files are stored. So, when a student launches the app, the first thing they'll do is go to the settings tab to tell the app where to store and find his/her files.
For Windows, you will need to un-install and re-install the software to activate these changes. For Mac, you will just need to drag the new software into your Applications folder and let it overwrite the old one.
