Hybrid and Structure have always been, and still are, separately purchased programs.
What comes free with PT10 is Structure Free, Xpand2, Boom, DB33, Vaccum, and Mini-Grand.
If he had Hybrid and Structure (perhaps LE?) working in an earlier version of Protools, he probably had the Music Production Toolkit, so he would still have Ilok licenses for those, and would need to download the installers from here:
