Drop the contents of the zip file inside your game folder at:
...\Steam\steamapps\common\Super Street Fighter IV - Arcade Edition\patch_ae2_tu1\battle\chara\DSM

If this folder doesn't exist, just create it.

The mod shouldn't overwrite any file, but make sure to have a backup of your original files before installing the mod.
