If you bought it from a reseller, they should be able to tell you.
AFAIR there were two libraries, one that contained all the building parts, chinking, stacking elevation info, corner objects, database stuff, etc and had a name like LHS 1.7 Library. And then there was another one that contained appliances, doors, furniture, lamps, trusses, windows etc and had a name like LHDS R5 Library.
I thought they both came on the LHS CD. The person who sold it to you is the best resource for this info. Otherwise US resellers Chris Clark or Angi Sams may be the next best alternative.
