~How to install a program (Palm Desktop) that is completely SHARED between 2 different PC login users, but not by all other users on my PC? 

 

~I am using Dell's Dimension 4700 with Windows XP Pro.

 

~I can get the software installed on my login (I am the administrator).  But, I want my wife (a different user with a unique login) to also have total shared use of all the program and its data.
