Cannot find 3dsMax script in either 4.5.1 or 4.6 Extras

Hello, as referred to by this doc page: I looked in the folder for both 4.5.1 and 4.6 installs and the folder “FX_tools” folder isn’t in there, but I do have the maya tools and the 3dsmax pivot pointer and visual studio stuff. where can I get my hands on this script?
