In order to create a FotoShow, you must have DirectX 9.0 or later installed on your system. You can get DirectX 9 from www.microsoft.com or you can refer to http://www.fototime.com/pages/ftdownloads to get more information on how to install it.
DirectX 9.0 is only required on the systems that will be used to create the FotoShow's. Nothing special is generally required to play the created show.
