supressing reboot at end of admin distribution

We are deploying solidworks from our "admin image" which we created on our server using the command

sldim\sldIM.exe /adminclient /new /source %UNC%\AdminDirector.xml /norunsw

this all works fine and the software installs but right at the end it displays a box saying "Restart now" or "Restart Later" how do i get rid of this box as we are deploying a whole bunch of applications via a script and its requires someone to click the "Restart Later" button for the script to continue running

Cheers in advance
