[moneydance] installing in Ubuntu 8.10

[gordonsmall User]

This is embarrassing, but I will fall back on the only dumb question is
the unasked question.

I have been searching for a simple substitute for Quicken in Linux that
prints checks, and it looks like Moneydance might be the answer. I am
running Ubuntu 8.04 on an AMD 64 bit system, and Ubuntu is loaded under
Windows (Wubi installation). I am pretty new to Linux.

I downloaded the Linux version of Moneydance via Firefox, and then
double clicked the file in the download manager, which seemed to extract
the file.  However, I could not find a file where the program is now
located.  My saved downloads go to my desktop by default, but it is not
there, or any other file or directory that I can find.  When I search
for Moneydance, it says no such file found.  I downloaded both Java
versions with the same results. My package manager says I have "java-
common" installed.

Can somebody give me more specific information on how to get Moneydance
installed on this operating system?
