quiet install of forticlient with mst and accept eula on Windows 7 SP1

Dear everybody

Please can you tel me what is a correct syntax to run a quiet install forticilent.msi with mst file with accept EULA.

I already tried msiexec /i \\srv-lan\install\forticlient.msi /t \\srv-lan\install\fc.mst /q /ACCEPTEULA or ACCEPTEULA=1 or ACCEPTEULA=YES or ACCETEULA=TRUE but unsuccesffuly.

It still ask for click accept Eula and  no settings (from mst) applied.

Thanks for all

Georges
