Win 7 After uninstalling Firefox from Control Panel, "The action can't be completed because the folder or file in it is open in another program"

Update failed numerous times. Uninstalled FF using Control Panel. Followed instructions to delete the Mozilla folder from AppData/Local/Mozilla. Then the "Folder in Use" prompt comes up and I have to cancel the delete. Folder was created 4/8/2011, but I can't find the folder using the search command. Can't install a fresh install of Firefox 18. Using Windows 7 64-bit. I no longer have FireFox on my system that I can see.
