The 'specified module' is specified in a pop-up (but not on Win 2000
ans sometimes it gets hidden): this is a Windows error message, and
confuses many people.
You need Sun Jave installed and in your path, and you need a 32-bit
Java, not a 64-bit one. My guess is that the problem is one of the
conditions of the previous sentence.
