Place hkx converter "SSFADF.exe" (sorry that was a keyboard-mash name) in root of hkx animation directory, double-click, it will recursively search for all animations (*.hkx except Skeleton.hkx and Skeleton-out.hkx)
use hkxcmd http://www.nexusmods.com/skyrim/download/37272 to convert Skeleton.hkx file to Skeleton-out.hkx
*.damnhavok files are importable in noesis, copy the dll to your noesis plugins folder (where the other dll's are), NOTE: the plugin expects a "Skeleton-out.hkx" file (that exact name) in the same folder as the .damnhavok animation file being opened.
when exporting from noesis, make sure you use fbx as both "Main output type" and "Additional animation output"

new: if you want to extract root motion, be sure to convert all the .hkx files with hkxcmd (hkxcmd convert "path_to_hkx_files_folder")

UPDATE: PLEASE RE-DOWNLOAD DLL

Boss/Map Extractor

Extract chr/c4100.chrbnd.dcx (Artorias) with BinderTool.exe (drag .dcx file on .exe)
Unbind with Gibbed.DarkSouls.Unbind.exe (drag .bnd file on .exe)
Copy \bdtTextureExtractorv1.1\chrtpfbdt.exe to ~\dvdbnd0_unpack\chr\c4100.chrbnd\c4100_unpack\FRPG\data\INTERROOT_win32\chr\c4100
Copy the right xml file from xml.zip (\xml\c4100.xml in this case) to ~\dvdbnd0_unpack\chr\c4100.chrbnd\c4100_unpack\FRP G\data\INTERROOT_win32\chr\c4100
drag the right xml file (c4100.xml in this case) on top of chrtpfbdt.exe (for bosses) or tpfbdt.exe (for maps)
In the same folder will now be .tpf.dcx files, extract with BinderTool.exe!
Unbind tpf's with Gibbed.DarkSouls.TextureConvert.exe

Hint: there are many .tpf.dcx files, a way to deal with that:

select all the extracted .dcx files
shift + right-click -> copy as path (only appears with shift in explorer context menu)
paste in a text editor with find + replace function
_find the _starting-two-characters* and replace with the path to "BinderTool.exe" space + starting-two-characters
save as .bat file
double-click .bat file
Do the same for the tpf's with TextureConvert.exe

Requires a "Skeleton-out.hkx" to be in the same folder as the .flver, this file contains the skeleton information that is used, the file flv has shit skeleton data
Use hkxcmd to convert Skeleton.hkx (binary skeleton) to Skeleton-out.hkx (xml)
