Office2003 Silent install command

setup.exe /qb+ /l* %temp%\office11.txt COMPANYNAME="Northwind Ltd"

This command line customizes Setup in the following ways:

• Setup does not prompt the user for information, but displays progress indicators and a completion message when it installs Office (/qb+). To disable message, use /qb-.
• Windows Installer logs all information and any error messages (/l*) for Setup.exe to the file C:\Documents and Settings\<Username>\Local Settings\Temp\Office11.txt.
• Setup sets the default organization name to Northwind Ltd.
• Because no custom INI or MST file is specified, Setup installs the same Office features that it would if the user clicked Typical Install in the Setup user interface.

Similar command may work for Office 2007/2010/2013.
