SmartTools.WhatsNew leaves missing references when removing feature.


With 2007 I am doing a preupgradecheck and it reports Path = [C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\Template\Features\SmartTools.WhatsNew\SmartTools.WhatsNew.webpart], Reference = [2], Status = [Missing]
I've re-installed and then uninstalled and tried other tricks with the exception of going in to the actual databases and removing any references. Only thing stopping me from doing this is I'm not sure where I should look in the first place.
Any ideas on how to get rid of this error?
