Problems upgrading from home premium to ultimate

[Corporal Clegg]

I recently purchased a vista ultimate upgrade and I am trying to install
it on my home premium pc. When the installation gets to the point where
it asks what type of installation I want, the "Upgrade" option is
greyed out. I have installed windows upgrade advisor and it says my
computer is ok for ultimate. Both the disk and my computer have SP1 on
it.

I have Norton 360 on my computer, but microsofts site says that Norton
is ok to have while upgrading; at the same time I'm fairly sure that
this is why I'm not being allowed to upgrade, but I'm not sure.

Install it from within Vista.
