Error 14001: The application has failed to start.

A client called and notified me of an error on their production server running NAV 2015. The error reads thus:

{Windows could not start the Microsoft Dynamics NAV Server [DynamicsNAV80] service on Local Computer.
Error 14001: The application has failed to start because its side-by-side configuration is incorrect. Please see the
application event log or use the command-line sxstrace.exe tool for more detail.}

Apparently, the NAV server stopped and couldnt restart. It also give this error if you try to edit the service in the NAV Admin Tool:

{
Configuration file error:
Data at the root level is invalid. Line 1, position 1. (C:\Program Files\Microsoft Dynamics NAV\80\Service\Microsoft.Dynamics.Nav.Server.exe.config line 1)}

I search everywhere online but i didnt get a solution so, after resolving it, i thought of sharing the solution in case anyone faces same problem.

Solution:

Go to the installation folder to copy the Microsoft.Dynamics.Nav.Server.exe config file and replace it in the following path:

C:\Program Files\Microsoft Dynamics NAV\80\Service\

It will replace the existing one. Then restart your NAV Server. It should work.
