What version of Office are we talking about?
I have been trying to get one of those gray-market keys from Groupon working, but that has proven to be very difficult because there's a lot of weird kernel-level stuff going on for verification because those are done with volume-licenses. If I were willing to pay full-price for a regular Office 2024 Home and Business key I think it would be relatively easy to adapt this to get it working, but I don't want to sink $200 for software I'm unlikely to ever actually use.
