I thought I would share some useful information I found out about distributing software that uses the install shield. Below are some commands that can be ran against a software package that uses install shield. The first command creates the iss answer file. While the second command allows you to install the software using the answer file. See the link for additional details.
Recording the response file
DSSAC_setup.exe /r /f1c:\temp\DS2.iss
Installing with response file
DSSAC_setup.exe -s -f1.\ds2.iss
The above assumes that DSSAC_Setup.exe is in the same folder as the DS2.ISS
