I received the rendering library is not installed message when I loaded Revit 09 Structure. I saw the troubleshooting info that said to download the protien file and so thats what I did. I downloaded it to my office server so that others could acess it in the office if needed. It came over as a Cab file and I cat seem to get an extract option off it, and revit wont recognize. I went into the file itself and extracted 4 individual files but they did not extract as .fbx and were of no use to me. Any direction would be appreciated.
