Marisa,
This particular example requires Microsoft's ActiveMovie Control version 2, which is old and most likely not installed on your computer. I have attached a revised example that uses the Windows Media Player instead.
To use the Windows Media Player or another viewer (RealPlayer, QuickTime, etc.) in your application, simply right click on the front panel and place a ActiveX container. Then right click inside the container and insert an ActiveX object. You will see a list of all objects available on your machine. Choose the viewer that you would like to use. Later, when you create property nodes on the block diagram, LabVIEW will know which properties are valid for the object you are using.
