Malke is saying that you cannot perform an upgrade in place when migrating
from 32bit Windows to 64bit Windows.
The upgrade license you purchased allows you to install Vista x64 on a
computer with Vista x86 using the upgrade edition product key, but you will
have to boot with the 64bit dvd and perform a custom install to do it.
Since the Vista x64 setup program is itself a 64bit program, it cannot be
run from your current Vista 32bit desktop. That is why you have to boot the
system with the 64bit dvd.
What Malke is talking about as a clean install is formatting the target hard
drive or partition to get rid of the old operating system before installing
the new one. You can do that if you wish since you are installing a 64bit
version of Vista and are booting with the dvd. The custom install is all
that is necessary however. The term "custom install" is something you will
see during installation process so choose it when the option appears. The
"upgrade install" will be greyed out.
A custom install does not preserve your apps, files, and settings so use the
Windows Easy Transfer wizard to save your files and settings to intermediate
storage (a second hard drive or a dvd), install Vista x64, reinstall your
apps, and then run the WET wizard again to restore your files and settings.
You will need to download the 64bit drivers and utilities from the computer
or device manufacturers' website and save them to a cd before beginning all
of this. Most of the drivers may already be on the Vista x64 dvd, on the cd
that came with your computer or motherboard, or available from Windows
Update following installation of Vista x64, but plan for the worst case
scenario which would be that you would have to go find them all yourself.
