Performing an Unattended Installation of Reporting Services
Performing an unattended installation can only be done from the command prompt. To perform an unattended installation of Reporting Services, run setup.exe from the command line, and specify the /qn argument to suppress the graphical user interface. The /qn provides for a silent installation, displaying no user interface dialog boxes. For more information on running setup from the command line, see Installing Reporting Services from the Command Line.
When installing the components, there are groups of properties for each component that must be specified and have values in order for the installation to succeed. This is true whether the installation is a new installation, or whether the component is being added later.
For a list of the available properties for each component, see the ADDLOCAL parameter in Installing Reporting Services from the Command Line.
