Download ExcBuilder v2 here-http://www.scenery.org/design_utilities_b.htm-extract to a folder of your choice. Simple instructions in the readme... file.
Download the FS2004 Bglcomp SDK here-http://www.scenery.org/tutorials_fs2k4_SDK.htm-Run the installer. It will install files, including bglcomp.exe.
These are for FS2004 scenery design. Different downloads are required for FSX.
If you're project(s) include a new airport, or putting your missing town 'on the map', there are other tools that may be required for flattening, land class, and object placement. While there are small programs that can do each, the Sbuilder program can do it all.

I have just downloaded the ExcBuilder, and the BglComp SDK; however, if you or anyone else could please point me in a direction for a "FS MotorGrader" Land Flattening program and one that could allow me to put my new airport on a map I would worship you as an FS God!
Thank you in advance
