For this demo, you need Delta3D 2-4-0.
Make sure that DELTA_ROOT environment variable is set to the root directory and that the path can access the Delta3D dll.
Add that to the user path: %DELTA_ROOT%\build_VS2008\bin;%DELTA_ROOT%\ext\bin
Do not mix OSG 2.8 and Delta3D dll, change OSG directory name before running any Delta3D sample.
