Rating would be higher if I could be able to run Polymath. You can consider the book useless if you are not willing to pay for this software. In my case, I paid for the software but not successful during installation, it returns an error. Unsuccessfully trying to contact customer support (only options are by email or regular mail). No answer yet. Should not sell the software if no support can be provided.
