Hi there,
I´d like to ask for some more background information:
- is on that specific machine ArcGIS as well running? If yes, which version?
- ArcGIS also connects to your license server? If yes, does it start correctly?
Opening ArcGIS Administrator you can see on tab Availability the concurrent use licenses of your license server for City Engine 2012?
Did you try to open CityEngine as Administrator? Same error message?
- You recall as any change the update of your campus license. No other other changes of that machine, correct?
Kind regards,
Anna
