Recently we deauthorized two ArcGIS Desktop Standard Licenses out of total five from one server (ArcGIS License Manager version 10.4) . After that when we are trying to open ArcGIS 10.2.1 and 10.3.1 pointing to that license manager server we are getting error message "Problem connecting to License Manager. Error Code = -8. Flexnet Licensing Error = -8,544. ArcGIS for Desktop 10.3 cannot connect to previous versions of the ArcGIS License Manager."
Can anyone help on this?
TIA
