I recently install Autodes Civil Cad 2013 and 2012 in my PC wit windows 8 and the program crash every 5 to 10 minutes, does somebody knows how to fix this poroblem????
Try a Google search. You are not the first to attempt to use C3D in Win 8. You my find a way to get it working.
Just as an FYI, a local client was having the same issue. We had him uninstall Civil 3D and then re-install using Windows 7 Compatibility Mode. Now he's up and running and has reported no crashing.
Actually, Autodesk has said they will support Windows 8 users.
C3D 2012 & 2013 is not stable on Win8. Most report C3D 2013 with SP1 works well.
I am running it on Windows 8, WITHOUT SP1 and it works fine. However, it is not supported.
