Ever since I installed Civil 3D on my Windows 7 64-bit machine, I have not been having luck inserting .sid files. That is until today. Here is what I did:
Uninstall ALL AutoDesk Civil 3D Object Enablers
Reinstall 32-bit raster_design_2010_oe_32_eng
Run as administrator
This time I had no errors in the installation
I can now import .sid files with no problem. I know this is essentially the same process as the last post, but it did work for me. Hope this helps.
