Hello Gentlemen,Will the deployment of office 2007 through MSI replace the current office 2003 installation on our workstations?Thank you for your time and feedback.

Please read here: Setup files In previous versions of Office, each product consisted of a single Windows Installer package (MSI file). The chief role of Setup.exe was to call Windows Installer (Msiexec.exe) to install the package. Because Setup passed its command line to Windows Installer, it was possible to manage the installation process by setting Window Installer properties on the command line. In the 2007 Office release, a single Office product comprises multiple MSI files. Setupnot Windows Installercombines the language-neutral core productpackage with one or more language-specific packages to create a complete product. No individual MSI file represents a product that anyone can install or use, and Setup is required to assemble the correct set of MSI files and to coordinate the installation process from beginning to end. The Office product that you install is defined in the XML files on the installation point. Setup reads data in these XML files, assembles the required set of MSI files for the product, copies all the necessary files to the local installation source, and only then calls Windows Installer to complete the installation process. http://technet.microsoft.com/en-us/library/cc179022.aspx And then you can look at your options here: http://technet.microsoft.com/en-us/library/cc303395.aspx (You likely want this option: Using enterprise deployment tools)
