Hi guys :D

I just got a final version (The one that arrives on october 22nd) dvd with Windows 7 Ultimate, with both 32bit and 64bit..

But my problem is that everytime i choose 64bit installation in the installation menu, and then choose upgrade, it compatibility checks my pc, and then it says that i cannot install, because its not the same architecture, even tho my pc is able to upgrade to the specified version!

Well, i should be able to upgrade from vista ultimate x64 to 7 ultimate x64, without doing a clean install?

If anyone knows how to solve this, please reply :)

Oh yeah, my OS i windows ultimate 64bit...

Thanks
Jake :D

Run setup while in Windows and you can.


If you run Setup from within Windows:

You can upgrade Windows Vista or Windows 7 Build 7077 or later.
You cannot run x64 Setup on a system running an x86 build of Windows, or vice-versa.
You cannot upgrade Windows XP or any pre-7077 build of Windows 7 (unless you use the workaround I describe later in this post).
You can install Windows 7 on the same volume as an existing Windows version. (I describe the best way to accomplish this in #4.)
You cannot make any changes to the layout of a disk; you must use existing partitions, and Setup will not recognize unallocated space.


If you boot from the Windows 7 DVD:

You cannot upgrade an existing Windows version. Your only option is a custom install.
You can delete existing partitions, create new partitions, extend an existing disk partition to unallocated space, or designate a block of unallocated space as the setup location.
You can install Windows 7 on the same volume as an existing Windows version.
