How do you remove a VST engine from Cubase's list?

Hello, Cubase 8 still sees Kontakt2 in the Rack Instruments VST list, I want to erase that, how do I do it?
I tried plugin manager, but I cant delete it. I now have Kontakt5.


Uninstal !?

I have uninstalled it, but it still shows up, and if by mistake I select it, it gives an obvious error message, so I just want to get rid of it from the list of VSTs

locate the .dll - file and delete it mnanually !?

Rather than do this, (if the dll is not causing problems) you can explore the new Plugin manager, here you can set your own custom view of your Vst list
