Note for Users of Microsoft Windows Internet Explorer
Microsoft Internet Explorer does not contain support for Java applets. Many SEAsite exercises are implemented as Java applets. The lack of support is due to ongoing wars between Microsoft and Oracle Systems (which now develops Java). We will not explore this issue here, but note that it is easy to add Java support to your Internet Explorer.
Google "Java Plugin for Internet Explorer" or something like that and you will be able to find instructions on installing Java. You will only need the "JRE" version. The "JDK" version is larger but will also work.
You may need administrator privileges to do this.
