sw 2003 and silent install

hello

i'm trying to install solidwork 2003 silently.

so i do

setup.exe /r

i get a setup.iss file

when i use it setup.exe -s -f1"c:\windows\setup.iss"

i got

[InstallShield Silent]
Version=v6.00.000
File=Log File
[ResponseResult]
ResultCode=-3

if I try setup.exe  -f1"c:\windows\setup.iss"

not silently

it looks like it doesn't read the seond code (after serial)

[{606D713B-B60C-11D6-A47A-00B0D03E4223}-SdShowDlgEdit1-0]
szEdit1=XXXXXXX
Result=1

is it an installshield  bug ?

any workaround ?

setup.iss in attachement

thanks
