Hey Rob,

BusinessObjects Enterprise XI 3.1 application is a .MSI (Windows installer application) and
if you can use .MSI file (Out there inside the folder) with command line option /qb or /qn.

Following steps describes creating  customized ini file for deployment purpose.
 

Open a command window and change to the directory containing the BusinessObjects Enterprise setup.exe program.

Launch the BusinessObjects setup program by entering the following command:

setup.exe -w filepath\filename.ini

where filepath is the location where the script file will be generated And filename.ini is the name you give to the INI file.

Note: The -w option tells the installation program to write your installation selections to an INI file.

Run the silent installation by entering the following command:

setup.exe -r filepath\filename.ini

where filepath is the location of the INI file filename.ini is the name of the INI file.
Note: The -r option tells the installation program to read installation parameters from the INI file you specify.

Thanks,
Munna
