(My english is bad)
Thank you for your answer.
I tested the 2 possibilities in Windows XP SP2 Pro Fr and here the conclusions:
1. When one selected to install all the shortcuts for all the users, it is there only one short cut created on the desktop for “All Users”, nothing in the start menu and nothing in quick launch.
2. When one selected to install all the shortcuts only for me, there is a shortcut created in the quick launch and on the desktop of the user, but the group of program is created in "All Users" !!
Some corrections to be made…
