Cannot remove plug-in RhinoJewel 6 trial

I have installed RhinoJewel 6 trial version, and cannot get it to uninstall. Although I used the program to uninstall it, and it does not show in Plug-ins anymore, it still has a menu on the top bar next to help. Can anyone please assist?
Kind Regards

delete - unload rui file?

It sounds like the plug-in is in fact gone.
You still need to remove the “tool tray” that the missing tools were in.
That’s deleting the RhinoJewel toolbar file in:
Options > Toolbars.
Default is the one for Rhino.

Many thanks all!
That did it!
