Yes, have seen a few users experiencing the issue now, but have not seen the issue happen myself on any computers I've tested it on. It's happening due to the app needing to find the installed versions of AutoCAD Civil 3D in order to find the correct version of AcCoreConsole.exe that is uses on the backend. It seems, in some situations, that registry entries are not being fully cleaned up on uninstalls of previous versions of AutoCAD Civil 3D. Not sure of the reason, but that is causing the app to fail at launch as it cannot find the installation.

You'll need to look through the registry location and check the versions there and confirm if they are installed or not. If not, remove the registry entry and the app should run. For now, that seems to be the only solution.
