Here is the FULL unlocked version of Hook 5 (which Pervo publicly released after "ModsGarden" went down. NO KEY REQUIRED.
You will still need your video card driver to download & install the necessary "PhysX" files to support Hairworx/moving hairs, but everything else is included (including hairs.)
(I added a short "minimum install" text file for the bare minimum to get Unlocked Hook 5 installed & working [w/o PhysX hairs].)
Download from MEGA (24MB).
