Hi -- Just got RX7 -- it's installed in my system (VST3) and working fine with DAWs, etc. Same with Insight 2 and Ozone 7.
I've added the path C:\Program Files\Common Files\VST3 and nothing showed up after a restart of Resolve (even though all the relevant directories are in fact all there.)
Then I added C:\Program Files\Common Files (x86)\VST3 and the plugins all appeared in the list at Preferences -> Audio Plugins -> Available Plugins, and I enabled them, and restarted Resolve.
But the plugins still do not appear in the drop-down menu to add them, and they have apparently been automatically unchecked in the Available Plugins list.
I searched through the diagnostic logs and found nothing...
