Hmm, should I mention that activation might require contacting Microsoft Support if automatic activation fails? Yeah, phone activation is an option for the wizard if the internet isn't working. Also, some users might have corporate licenses, so volume licensing isn't covered here unless specified.
Then, guiding them through the activation process step-by-step would be helpful. Make sure to note that Windows XP or Vista is required since Office 2007 isn't compatible with newer OS versions. Also, if they're on a newer OS, they might need to use compatibility modes or run through a virtual machine, which I should mention.
Common issues they might encounter could include error messages like "Product Key Invalid" or "Activation Failed." For each issue, I should suggest troubleshooting steps like checking the product key, ensuring internet connectivity, using the Microsoft Activation site, or manual activation by phone.
