Install Problem

Hi.

Trying to install ForeFront Server Security Management Console on
Windows 2008 Std x86, i run setup.exe, select "Standalone" then
"enterprise" and then press "check prerequisites" and it lists 3
things to be installed, press "yes" to install them it flashes quick
as if to install, then back to the screen again about checking
prerequisites, does not continue the installation.

Any Ideas ?

Thanks
