We have tried to make the CD as portable as possible. All animations are encoded in AVI format using Cinepak compression (no audio track).

Make sure your have at least version 3.0 of Navigator or Internet Explorer. The latest versions of these browsers for a variety of architectures can be downloaded from Netscape of Microsoft respectively.

For Windows 95 users, the following steps will enable you to check if you have the Cinepak video codec installed :

1. Access `Add/Remove Programs` in the `Control Panel`
2. Access `Windows Setup` tab.
3. View details of the `Multimedia` entry.
4. Check if the `Video Compression` component is installed? If it is not please do so.

Navigator/Internet Explorer on Windows 95/NT and MacOS

- Netscape : Assuming your plugin works the left mouse button will play the animation, and the right mouse button brings up the options menu.
- Internet Explorer : Assuming you plugins are working and the page with the animation still appears blank, there are two options you need to check.
  1. Choose menu View/Options. Click on the General tab. Are the `'Show pictures'` and `'Play videos'` options on?
  2. From the View/Options dialog box choose the Security tab. Turn on the `'Enable ActiveX controls and plug-ins'` entry.

UNIX

For UNIX based operating systems the situation is a little more complicated. First check if your vendor supply multimedia programs capable of playing AVI animations.

Xanim can be used but the Cinepak codec is only available for certain architectures. Please check out the Xanim home page and liase with your local System Administrator.
