Numerical Innovations - Help Center

Our tools natively converts DXF files (eg: import/Export).  However if a user wants to import a DWG, we use a 3rd party tool to convert the DWG -> DXF in the background.  That message means the component ../bin/Activeconverter.dll wasn't properly registered during installation - here's more information, https://support.numericalinnovations.com/support/discussions/topics/14000019602

I would recommend trying to either re-install again and see if that registers the component, or just import as a DXF file instead of DWG  (DXF and DWG are essentially identical except DXF is ASCII. Plus. DXF is the most widely used CAD format.)
