Caller, Marvin, needed to have a program he installed in his user account be available to his wife and daughter. Here's the solution:

1. Make sure that when installing a program if the program gives you the option to install to just you or all users, choose All Users.

2.  IF, that doesn't bring up the icon to the other users, RIGHT click and choose Copy on the program's icon, then Click My Computer, double-click "Shared Documents", Click Edit --> Paste. Now you can log into each of the other users, and copy that shortcut to the desktops of the other users who need access to the program.
