I'm running the same, 10.12.6 and VMRC 10.0.1 setup. the VMRC doesn't do anything by itself, Launch a web browser, I used Chrome, we have a vCenter server to which we connect. That opens the vSphere Client window (using html5, not flash). Select a virtual host and double click on the console window just below the Summary tab. I was prompted on what application to use, I navigated to the applications folder and chose the VMware Remote Console (VMRC), that took me right into the console that I was looking for, there is a dearth of info and this process. In essence, the VMRC is a plug-in or a helper app which runs inside a web browser, I haven't tried Safari or Firefox at this time as I just got this working about 30 minutes ago. I need to make this work on a PC as well.
