Country Kits for Autodesk Civil 3D 2027 have the following known issues:

Unsigned Executable File Message when launching reports:

• Some Country Kits may display the following message when launching a report or tool from the Civil 3D Toolbox: "The publisher of this executable file could not be verified and the file is not located in a trusted folder. What do you want to do?" If you select Always Load, the message for that report or tool will not recur. For Country Kits with more than one unsigned report or tool, this dialog may appear once for each report or tool. Alternatively, you can add the report or tool location to Trusted Paths in Civil 3D Options to allow it to load without displaying this message.

Reports or Tools that are incompatible with .NET 8 or .NET 10

• Starting with Civil 3D 2025, .NET-based add-ins, tools, and reports are required to be compatible with .NET 8. Starting with Civil 3D 2027, .NET-based add-ins, tools, and reports are required to be compatible with .NET 10. Autodesk has made a best effort to ensure that each Country Kit is compatible with the required .NET version for its Civil 3D release. However, some legacy reports and tools, especially those launched from the Civil 3D Toolbox, may be incompatible. These reports and tools are expected to be updated or replaced in future updates or releases. If a report or tool fails to launch, check whether an updated Country Kit is available from your Autodesk Account or contact Autodesk Support.

Files Removed at Uninstall

• If you modified any installed Country Kit files, back them up before uninstalling the Country Kit to avoid losing those changes.
