As always if you have any problems at the end of this guide you can contact your local technical support or our Twitter team for further help, but in this case I would recommend you contact your local Microsoft helpline instead.
If it's a authentication issue, Microsoft are the only people who can check and affect this. Dell can't supply new product Id's for ones that have been lost and we don't have the access or authority to authenticate your office install.
If it is a particular installation error code, Microsoft are the people who will have the best idea of what it means and how to resolve it.
If you are having licensing errors or have questions about it, again Microsoft will be the only people who can check and go over this with you. Dell doesn't have access to license lists or to how many machines are reporting that particular serial or license at the one time. We can't check how many times that license has been used or on what systems.
