To install this setup you will need the original FXAA Injector mod.
Download from here:
http://www.skyrimnexus.com/downloads/file.php?id=131

You will need all the files and folder, except the readme.txt for the mod to run.
Extract all those files into D:\Program Files\Steam\steamapps\common\skyrim
or where ever your Skyrim is located.

Once done take the injFX_Settings.h file from me and replace the one you
just put into your game.

Finally take my SkyrimPrefs and place in to:
C:\Users\YOUR PC NAME\Documents\My Games\Skyrim

Don't forget to make a backup of your original files as this is designed
for a mid-high end PC setup.

Known bugs:
With FXAA if your game is crashing, make sure you don't have monitoring tools
open, such as FRAPS, Xfire ect.

If your game won't get past the launcher, then there is something in the
injFX_Settings.h file your computer dosen't like.

Note:
You need the provided d3d9.dll for this mod to work.
You can enable and disable ingame by pressing Pause/Break.
