The Program has been authored using Macromedia “Director”. The resulting software runs on both Windows and Macintosh operating systems up to OS 10.6 ("Snow Leopard"), but both require Quicktime™ to be installed in order to see the video clips. Quicktime™ is free and can be downloaded from:-http://www.apple.com/quicktime/download
"Director" is now obsolete and we are working to develop the key as a web-only product. Consequently there is no longer any support for the downloaded file.
