@Anonymous,
Ok, I looked at your CER that your screencast demonstrated...Did I say thank you for making those, because they are invaluable in a forum setting. I know that many think those CER's just go away, but they are priceless to tell us what context the error occurs.
I see you are running Windows 8 SP0 which historically has demonstrated to to capture 17.59% of the exact same contextual errors you are exhibiting. Also if we look at minimum System requirements for AutoCAD Civil 3D 2017 we see that :
- Microsoft® Windows® 10
- Microsoft Windows 8.1 with Update KB2919355
- Microsoft Windows 7 SP1
Those are the minimum OS requirements for the.
So if you were able to update you OS to the Microsoft Windows 8.1 with Update KB2919355 it would decrease the error bucket down to 1.93% from 17. 59% which is a good solution vector to begin with.
I also see that your Graphics card (GeForce GTX 760/PCIe/SSE2; 4.6.0 NVIDIA 398.36) is not shown in the recommended graphics requirements. Sometimes these things don't make any difference, until, they do.
Could you try to update the OS to the next version, being 8.1 with the KB and see what that accomplishes. I can't say what has changed in your environment within the last couple of weeks. But I would like to help you get back to a workable suite.
