Internal Error X in Module X

NAV internal error messages

Internal Error X in Module X error messages come from C/Front and the Dynamics NAV Database.

These errors are not coming from the Jet Excel Add-In.

Most "Internal Errors" are the result of an incorrect version (build) of NAV's C/Front being installed. Updating C/Front (part of the NAV SDK) to the correct version will resolve many of these errors.
