Command line installation not installing licence server details

Hi,

I have a problem which is puzzling me. I have configured and application by importing the .msi file and obviously tested the command line first to make sure it works:

msiexec /i DRS11x.msi /qn reboot=reallysuppress SILENT=yes INSTALLSTANDALONE=0 CENTRALSERVERHOSTNAME=LICSRV1

But when I use the same command line in SCCM, it deploys the software, but does not register the CENTRALSERVERHOSTNAME which is critical as this is the license server for the software we are trying to install (DameWare).

Am I missing something in the command line?

Thanks.
