928116 How to determine which version of a 2007 Office product is installed
This issue occurs when you cancel the installation after some components have been installed. The service pack installs as a series of updates to the Office components. Canceling installation does not roll back service pack updates to any Office components that have already been installed.
To resolve this issue, complete the installation of 2007 Office Suite SP1. Or, you can uninstall and then reinstall the 2007 Office system.
2007 Office Suite SP1 includes multiple updates (.msp files) that are applied to the cached .msi files for the installed 2007 Office system programs. As soon as the first .msp file has been applied, and the next .msp file is being applied, any cancellation will roll back only the current .msp file.
