Hello @Jubbcardiff

It sounds like there has been a recent issue with AutoCAD 2017 SP1 and the Object Enabler 2017 affecting Civil 3D's ability to run.

It was resolved with installing Civil 3D 2017 SP1.1 after a clean uninstall of AutoCAD and all it's side-by-sides.

I was careful not to apply ANY updates until I had installed the Civil 3D SP1.1 first. Here is a link for your reference:
Install Civil 3D 2017 SP1.1 (readme) If you cannot access the file using that link you can download it through your Autodesk account. 

You may be able to simply install SP1.1 without a reinstall but this may not work. 

Thank you for taking part in our community forum! Please accept my solution if my post fully resolved your issue.

Kind Regards,

I had the same problem after applying SP 1 and the 2017 object enablers.  Tried uninstalling Civil 3D, but not AutoCAD.  This did not work, but applying SP 1.1 did.  I no longer have the problem.  Thanks for the tip.

Thanks that worked for me.

Thanks a lot...

Installing SP1.1.msp solved the problem without uninstall C3D.
