You do not have permission to run the 'System9110' system.
The majority of communications between Microsoft Dynamics NAV and the Jet Excel Add-In are handled by Dynamics NAV's C/Front utility (part of the NAV SDK).
This error indicates that your Dynamics NAV license or the copy of FIN.FLF in the Dynamics NAV Classic Client folder does not include the C/Front granule (#1800).
If you do not have the 1800 granule, contact your Dynamics NAV partner to obtain it.
The error could also be triggered if there are multiple Dynamics NAV Client folders and the correct license file is not in each.
