Systems Management

hi all,

in sccm 2007, how can i tell the user that, if the application i need to upgrade is open, he/she has to close the application?

i need to uninstall sap 6.4 before installing sap 7.2 all my tests are good except if sap 6.4 is open when the update starts.

i know how to make my vbs so it checks the process and if present, pop to the user. but in sccm, the popup is not showing on the screen.

how can i make my vbs popup from sccm, or some other way to make it happen?

thanks!
