I have attached the update ReadMe file to this post but will highlight the AutoCAD 2018.1 changes: If you have the 2018 version of these products, you can get it from the Autodesk desktop app or by finding it in your Autodesk Account. Update 2018.1 is available for Microsoft Windows-based AutoCAD and AutoCAD-based vertical products. See: AutoCAD 2018.1-based product shuts down when using DXF file with xref for more information about the problem and to obtain the hotfix file.Hello to AutoCAD customers on Subscription and Maintenance plans.

This problem typically occurs if you attach external references (xrefs) that have certain attributes to a DXF file.
