i generate one installshield.iss file with this switch:

(k=Dk) install mode desktop (k=Rc) invoke an unattended installation

\x86\setup\setupsql k=Kd k=Rc

Great create setup.iss in c:\windows

the problem if i use lines below to automated installations, setup try install Server - Enterprise Edition, but i need desktop.
\x86\setup\setupsql -f1 setup.iss -SMS
if i try like below, setup install desktop mode but don't execute
\x86\setup\setupsql k=Dk -f1 setup.iss -SMS

what can i do now ?
