My goal here is to have files that can be downloaded and passed around freely.
What I would like is to allow the user to be able to run the program 100 times
before running into limitations.  I would like for the user to not be able to
bypass this by deleting and re-installing the software.  This means putting
something in the Windows Registry most likely, and maybe 1 or 2 hidden files.
(By the way, date will not be an issue, but the number of times the program
is run will be.)
