Readishare printer 2.36 does not install on MAC Sierra 10.13.2 or 10.12.6

When I try to install readyshare printer 2.36 it says that the installation was complete and requires restart. After restart it says the installation was incomplete and does not work. I tried this on 2 different computers with two different versions of Sierra OS with the same result. By the way ... this discussion post website would not let me enter anything in the "Model (Recommended - Helps the community give the best answers" dialog box.
