Topaz Plugins

Hi Photoshop users. I have Photoshop CC 2015.5 and I'm having installing topaz labs. I currently have topaz adjust but I wanted to add the other plug ins. Anyone having a similar issue or know how I could fix this? I go through the process of how I would install the plugins if I didnt already have topaz adjust but after I do that I'm still stuck with only topaz adjust. Any help would be very appreciated.
