Navisworks exporter error Message from Revit

[Anonymous]

We use Revit Architecture 2016 and have installed the Navisworks exporter 2016 without error, but when we try to access the exporter from within Revit we get this error message

Error (must be addressed in order to continue)

Failed to open Navisworks exporter localisation file, please contact Autodesk technical support

Error 1

We have tried running repairs, uninstalling and re-installing and changing add remove features to try and get it to work.

We have the same installation on a different computer and it works without any problems.
