Good day, thanks for your question. I am glad to be able to provide assistance to you today. For this, a patch is not feasible anymore because Microsoft Autoroute has been discontinued last 2015 and hence you might want to look at a couple of alternatives or options below that might suit the setup that you currently have.
> QGIS (Free, Open-Source GIS Software)
> RouteXL (Free for up to 20 stops | Paid for additional/if needed more)
> Google Earth Pro
> Badger Maps
> Maptive
> Route4Me
> MyRouteOnline
> Scribble Maps Pro
> EasyTerritory (Can be integrated with Microsoft Power BI and Dynamics 365)
Regards,
Paul R.
