What is the full message of that error? I'm not sure what ID means either, in this context.

About your Microsoft Office Home and Student 2007, is it a full retail version, or is it a trial version?

Typically on new computers with software pre-installed we find a "Trial Version" of Microsoft Office installed. This is a 60-day trial, and after the 60 days is up many of the features are disabled. If that is the case here then you need to purchase the full retail version. Before installing I recommend you uninstall the trial, reboot, (restart), the computer, then install the full version.
