The Mac OS X version comes pre-bundled. All that is required is to drag the VIDA 2.1.2 icon to the desired location on the computer such as the Applications folder. Double-clicking on the icon will launch VIDA. The first time VIDA is run, VIDA may prompt for the location of the license file. If this occurs, there will be two VIDA icons in the Dock until VIDA is restarted.
To uninstall VIDA, simply drag the VIDA 2.1.2 icon to the trash from the folder in which it was installed. Nothing else is required.
