[users@httpd] Installing Smarty

[duluth]

As a PHP addition I downloaded Smarty-2.6.18.tar.tar. It requires installation 
but the install instructions assume a UNIX environment. I use Windows XP and 
tried to use the windows command install msiexec/i and got the message that the 
program to be installed was not a windows based application. 
 
Can someone suggest a solution? 
 
Thanks in advance,
