The ability for all users to access an installed program is a function of
the programs installation and not necessarily XP. If a programs installation
recognizes a multi-user environment, such as XP, it should give you the
option of selecting all users or single user during installation. Most newer
programs that are XP compatible will give you this option. If it does not
have this feature, you have several options.
You can try to create a shortcut to the program and place it in the
C:\Documents and Settings\All Users\Desktop folder. This will allow the
shortcut to appear on everyones Desktop.
You can use the Run As feature of XP by right clicking the executable file
for the program and select the Run As item. Set the user in the Following
User section.

You can re-install the program, while logged on to the other user accounts,
to the same folder where the program was originally installed.
