IIRC...seeing the morph but it not working is usually what happens if you inject the morph but haven't initialized the figure (run the BAT file). Not seeing the grasp morph at all means it hasn't been injected.

Make sure the morphs are in the same runtime as the figure. You will have to run the .BAT file again after you install any new DAZ morphs. And there's one for each DAZ figure, so you'll have to run the one for V4 and the one for M4. (M4 has two, the regular one, and one for his naughty bits, if you're planning to use those.)

V4 also has a V4V3 .BAT file. That one is for the V4V3 figure, which is V4's head on V3's body, for those who wanted to be able to use V3's clothing on V4. I doubt you'll be using that figure these days, but make sure you've run the right V4 .BAT file.
