Error: Configuration file required – Microsoft Dynamics NAV

Double click on the Dynamics NAV icon but open up this window? 



This error message pop up mainly because Microsoft Dynamics NAV cannot find the “ClientUserSettings.config” in the client computer. Most of the time Microsoft Dynamics NAV create this file itself and very rarely Microsoft Dynamics NAV will not be able create the file for you. In those kind of situations above error message is throw out.

Solution : As the solution for this, we need to create the file manually in the client side. You can copy the folder (from below path) from other user’s account and paste it in the below folder path: 

“C:UsersYourUserNameAppDataRoamingMicrosoftMicrosoft Dynamics NAV


Other option is to copy the folder from a older Microsoft Dynamics NAV version and paste it under above mention folder path and rename the folder for the correct NAV Version. 
Ex: If the version is 2016 then the folder should be named as 90.

Then open the “ClientUserSettings.config” file and change few values like below,

 <add key="Server" value="localhost" />  
<add key="ClientServicesPort" value="7046" />
<add key="ServerInstance" value="DynamicsNAV80" />


Once that is been done you will be ready to go.
