I have download the uninstall the the Arc GIS utility to erase my old AcrGis 10 and install the free trial ArcGis 10.1 but in the process of Installing the process fail to complete because a core licenses from a prior version exist on my machine, this I run again the uninstall utility and told me that everything from ArcGis 10 was erase. Now because of that "false" license it gives me only 15 days trial to unlock this feature.
What can this be and how can I get rid of it.

Thank you
