==Do I have Java? What version is needed?==

Most systems already have a sutiable JVM installed. In general, if you're planning to run on a pretty modern machine, a good start would be to ensure that you have the latest version [1.5] installed. However, any version from 1.1 onwards ''should'' work and earlier versions, being smaller, tend to load faster than the behemoth that is version 1.5 :-)

[As an example, on a Pentium 166 with 128mb ram, startup time for [[DecoderPro]] went from over 30seconds before the logo appeared to less than 10 when comparing Java 1.5 to 1.3. Of course, ymmv and a discussion on this topic is hopefully taking place on the 'discussion' page above!]

==Determining which Java is installed==

*Windows98: Go to 'run' -> 'Command' and enter 'cmd' at the prompt. This will open a new window with a prompt something like: 'C:>'. Enter (no quotes) "java -version" and it should return the version number of your installation. If some kind of error message comes back you're going to need to download Java from [http://www.java.com here.]
*Other Windows - Help!
*Apple Macintosh: Start a terminal window (Apps -> utilities -> terminal) and enter (still without quotes!) "java -version"
*Linux - If you're running Linux you know how to do this! :-)

==Do I need the Java development kit? (The 'Java SDK')?==

No, just the virtual machine!
