Upgrade from 10 to 10.1: What if the upgrade wizard is interrupted?

I have a user who was upgrading from 10.0 to 10.1. She had finished the installation and was in the process of upgrading her existing license (ArcInfo single use with 3D Analyst and Spatial Analyst) but lost internet connection in the middle of it. She then closed out of the “Query for Upgrade” box. Once we get internet access back, how do we restart the upgrade process?

Thanks.
