FYI, this is the solution that will have a list of of supported Autodesk products when they become supported on Windows 8. Please check back often as we add more products into the matrix:
This is a note from the the Being Civil team:
I know some of you have been asking about Windows 8 support for Civil 3D and the rest of the Infrastructure products. Just released is the current list of support Autodesk products on the new Windows 8 platform. At this time none of the Infrastructure products (Map 3D, Civil 3D, Infrastructure Modeler, etc.) are included in this list. The only one that is supported from the Infrastructure Design Suite at this time is 3DS Max Design.
