Installation methods vary depending on wood format and site conditions, but here are some general guidelines:
Engineered wood is typically glued down to concrete or plywood subfloors, with or without an underlayment such a sound abating mat or a moisture barrier, depending on site conditions/requirements. 
Engineered floors are also usually the best choice for gluing down over radiant heat installations.
In either format, when planks are particularly wide, gluing and nailing is always good practice if possible.
