No VST3 plugin available on this PC


I’m new to Audirvana, trying out the 30 day trial. I’ve used Roon for a number of years and have been a long time JRiver user. The appeal of Audirvana for me is its ability to use VST plugins. Now my problem, …

I have Sonarworks plugins installed but Audirvana tells me that ‘No VST3 plugins are available on this PC’. My Sonarworks plugins are clearly visible in the folders C:/Program Files/VSTPlugins and Program Files (x86)/VSTPlugins. Could it be that Audirvana expects plugins to be somewhere else? If so, where should I put the plugin so Audirvana sees it? Or is there some other problem?

Thanks in advance for any advice.
