Simply download both serp1.zip, and serp2.zip. Extract all the 
files into the same folder (for example, "C:\Program Files\Temp"),
and then run Setup.exe to install.

The game will be installed to the folder:
	"C:\Program Files\CentSoft\Serpent's Tooth"

It is critical that Serpent's Tooth(TM) is not installed to any other
folder, otherwise the save and load mechanisms in the game will not
work.
