I'm running a Windows 7 64-bit system with Autocad Civil 3D 2009 Land Desktop Companion and when I try to insert a Geotiff through the "Map" pull-down menu, I get the following error:
Cannot open frame
File: .\AcMapCoordinateTransform.cpp
Date: Feb 3 2009
Line: 221
I used to be able to insert the same Geotiffs on my Windows XP 32-bit running the same version of Autocad.
look at this thread

we do what it suggests, insert the image, save the file, exit autocad, reset the shortcut back to the original setting (there are other problems later if you dont), the restart autocad. once the image is in the drawing you are fine.
good luck.
