uninstalling Nattive Instrument demos

Is there an easy way to uninstall NI demos? I think they used to have an uninstall function, but I don't see it anymore. They take up memory and seem to be in a bunch of different locations. I don't want to risk screwing up any of my other Kontakt instruments. Thanks.

On Windows ?? Here is the page and Link I use whenever I have any NI Uninstall issues. Link is near bottom of page. ( NI Uninstall RegTool_64bit.zip ) There is likely a similar one for MAC ?

here is what I use.... can't say I could not live without it... but I would not want to... LoL
