Better yet, modify the abcpy.ini sections that deal with silents. For example:
[OEM Install]
ISX_SERIALNUMBER=xxxxxxxxxxxxxxxxxxxxxxx ( no dashes )
USERNAME=User
COMPANYNAME=OEM
INSTALLDIR=c:\progra~1\adobe\acrobat6
ALLOW_LOCKDOWN_BROWSE=YES
ALLOW_LOCKDOWN_MEDIA=YES
ARPHELPLINK=
ARPHELPTELEPHONE=
ARPNOMODIFY=
;ARPNOMODIFY=YES disables the "Change" button in Add/Remove Programs
Assuming everything is entered correctly, it will install fully silent. I then use a batch to move, rename icons, etc.
Thanks
