I'm sure this is a very simple question, but I've searched ArcGIS Administrator and Help and Support&Services to no avail.
I've installed ArcGIS 10.3 (Education trial, single use) but when I try to run ArcMap I get the following message: license manager running on host "Not_Set". When I go to ArcGIS Administrator it says "Not_Set" is an invalid host name, takes me to a box about concurrent use license and says I have 0 licenses and 0 available for ArcGIS Desktop Advanced 10.3.1. When I click on the data licenses box it is blank. See attached screenshots.
Not sure if my network administrator selected the wrong type of license; he doesn't think so.
Do I deauthorise? Uninstall? WIll my authorisation code still work?
