installing Bible desktop

[octotom]

I found a Bible Study program, called Bible Desktop, that I'd like to install and try out and compare with Bible time. I can't seems to figure out how though. It says that I need java and I'm pretty sure that I do, but I can't figure out how to install it.

Here is it's address:

Thanks!
