HP Z420 6-Core, 16GB, nVidia Quadro 2000, Windows 10.Uninstalled MC 8.8.  Installed MC 2018.7.  Launch MC Side note: get iLok errors.)  Once MC is up & running the Nitris DX is MIA.  Hovering over the HW/SW toggle, it says, "H/W S/W Disabled".  Video Inout Tool and Video Output Tool are both grayed out.  If I click on the HW/SW toggle, it lights up red, and says, "Broadcasting IP".  Video Output Tool is no longer grayed out, but brings up the sound options.  Uninstall MC 2018.7, reinstall MC 8.8, and Nitris DX is back.

Hi Randy, this is because from 2018.5 onwards, the DX driver is a separate install.

Thanks Job ... I completely missed that ... kinda buried in the ReadMe.
