Once the unzip procedure is finished, inside the QuantLib directory there must be the file QuantLib.m, which contain the programs of this Add-On, and the file PacletInfo.m, which is necessary to incorporate documentation in Mathematica's help system, and the directories  Documentation, Kernel and Binaries
