Re: Installing Vista Ultimate 64-bit
http://support.microsoft.com/kb/932795/
(My point about an upgrade PK is that you must revert to XP prior to using
it to install x64 from Vista x86.)
Copied directly from the Microsoft site:
Installing a 64-bit version of Windows Vista on a computer that is running a
32-bit version of Windows Vista
If you have purchased an Upgrade license together with a Windows Vista DVD,
you must use one of the following methods:
Method 1
Purchase a full version of the 64-bit version of Windows Vista.
Method 2
1. Remove the 32-bit version of Windows Vista.
2. Install Windows XP.
3. Install the 64-bit version of Windows Vista by using an installation
method that is listed earlier in this article.
If you have purchased a full license together with a Windows Vista DVD,
follow these steps:
1. Back up all the data and settings by using Windows Easy Transfer. Windows
Easy Transfer is available on the Windows Vista DVD. However, you must use
the version that is on the Windows Vista DVD for your currently installed
32-bit version of Windows Vista.
2. Insert the 64-bit version of Windows Vista into the system DVD drive, and
then restart the computer.
3. Start Windows Vista Setup from the DVD when you are prompted.
Note You must start Windows Vista Setup by starting the computer from the
Windows Vista 64-bit DVD. The installation package will not run on a 32-bit
operating system.
4. When you are prompted during Windows Vista Setup, remember to select
Custom as your installation choice.
5. When the installation is complete, you can restore the data from its
backup location.
