Windows vista to Windows 7 upgrade advisor tells me to uninstall Windows Defender but I can't

Solution
Windows Defender can not be uninstalled, but you might need to disable it - which it looks like you already have. Make sure all other antivirus software is uninstalled also, like Norton, Avast, AVG, etc. as these could cause issues to crop up when you are reinstalling.
