Cubase 9 error: Some content could not be loaded

Can anyone help me fix this error:

I tried looking for “HALion Symphonic Orchestra Factory Presets 01” in App & Features in Windows to uninstall it, but I don’t see that. I see “Steinberg HALion Symphonic Orchestra 64bit” and “Steinberg HALion Symphonic Orchestra VST Sound Instrument Set”. I think this particular version got installed with Presonus Notion.

Hi,

Hi,

Find the content in this folder:
C:\Users\YOURUSERNAME\AppData\Roaming\Steinberg\Content\VST Sound

And delete relevant vst sound files (HSO).
