Vista Upgrade "Requires clean install" help needed.

On the "Upgrade Paths from Previous Versions" page two "upgrade" paths are
presented; "Requires clean install" and "Upgrade-in-place".

If you want to install Vista Home Premium on a machine with XP Pro, you have
to do the clean install. If your machine has XP Home then you can do an
"install-in-place".

Can you use the Vista Home Premium Upgrade disc when you have to do a
"Requires clean install"?

Or does the Home Premium Upgrade ONLY work when the chart says you can do an
"Upgrade-in-place"?

No. The upgrade works for both.
