FortiClient Configurator Tool, which is used to create custom installers, will be available for download for free from Fortinet Developer Network (FNDN) site ([link]http://fndn.fortinet.net/).[/link]
This is different from FortClient versions 5.4.3 and earlier which required you to have a FortiClient license in order to use the full featured FortiClient Configurator Tool, but you did not need a FNDN account.
A few issues though. You need 2 sponsors to setup a FNDN account. The tool should give you an MSI file, but I'm not sure what the switches would be. I would try the standard MSI switches first "msiexec /qn /i forticlient.msi"
