Yeah, this is one of the "not so intuitive" things I mentioned
I actually have it setup at home to function properly, so will need to post back later. I'm 99% sure the POV-Ray install is optional (I don't think I had it installed when I started using the product), but you will need to download the Java runtime.
You can find the 1.4 JRE here:
http://java.sun.com/j2se/1.4.2/jre/install.html
And the 1.5 JRE here, which *should* work:
http://java.sun.com/j2se/1.5.0/jre/install.html - although I stuck with the 1.4 install, as I didn't even want to mess with anything that may not function properly where a Java app is concerned.
I'm not a big fan of Java, especially the demands it puts on end users to run yet another piece of software on their clients. I often forget what a pain it is deploying Java code like this package for both developers and end users.
Oh, and the second link above really is version 1.5.0, even though they title it "JRE 5.0".
If you're not averse to running the JRE, give one of the above JRE's a download --- if you're running Windows, I'll post a .bat/.cmd file you can use to call arbaro by placing it in the arbaro directory and double-clicking.
