I completely removed Cytomic’s “The Glue” and the NI “Solid Mix Series” from my Macbook, and yet the paths still exist. When I click them the program promptly shuts down.
If I go to Library/Audio/Plug-Ins/VST there’s nothing visible at all.
I can obviously deactivate the plugins in the manager and I won’t have to see them, but I feel like this is treating the symptom instead of the cause.
Any ideas? 
When you use your own plugin collections you have to delete it again.
If you use the standard (not custom) Pluginmenu it gets removed after uninstalling
Sorry, I don’t really understand. 
I removed the plugins and they’re still in the standard plugin menu.
I have the same issue: After removing plugins through windows 10, Cubase / Nuendo still shows them in the VST Plug-in Manager. When I try to select them in the insert nothing happens, obviously since I removed them. When I click on “Rescan All” it doesnt recognise the removed plugin. When I click on “Update Information on all Plugins” same.
