Removing plugins in 6

I have used the supplied uninstallers where available, uninstalled Rhino5, removed all that was related to Rhino 5 as per instructions here but I still get the message about plugins. They are not listed in Plugins, I have emptied Temp so what else I can try?

Hi - I’m not sure what you are trying to do.
When Rhino 6 tells you to update your Rhino 5 plug-ins, that’s just a reminder for you to check if any of the plug-ins that you used in Rhino 5 have an update for Rhino 6. You should be able to check a box to not see that message again.
