Windows 8 Upgrade 32bit to 64 bit

Hi,

I bought a Windows 8 Professional (Upgrade) DVD format with a 32 and a 64 disk

I upgraded my PC from Windows XP 32 bit to Windows 8 32 bit. However, I now want to install the 64 bit Version, my processor is x64 and I want to have all 32 of my GB of RAM usable.

When I inserted the Windows 8 Upgrade (64 bit ) I got a error message that said the my system is currently 32 bit and that i can’t use that install dvd to insert the other one.  Is There a way to upgrade from Windows 8 32 bit to 64bit?

Sorry, but that isn't possible. You can not upgrade to Windows 8 from
XP. Undoubtedly what you did was clean installation, not an upgrade.

However, I now want to install the 64 bit Version, my processor is x64 and I want to have all 32 of my GB of RAM usable.

You have a 32GB machine, and were running 32-bit XP on it? Are you
sure you have 32GB. Sorry to be skeptical, but that seems terribly
unlikely. First, you weren't able to use more than about 3.2GB of the
32GB. And second, it's highly unlikely that any machine form the XP
era would be able to have so much RAM installed.

When I inserted the Windows 8 Upgrade (64 bit ) I got a error message that said the my system is currently 32 bit and that i can’t use that install dvd to insert the other one.  Is There a way to upgrade from Windows 8 32 bit to 64bit?

No. There is no way to change the bitness of any version of Windows,
from 32-bit to 64-bit, or vice-versa. The only way to get what you
want is via a clean installation of the 64-bit version.

No. An upgrade from one platform to another is not possible.

 

You need to save your important stuff to a flash drive or whatever, and then do a clean install, booting from the 64-bit media...

 

Note that you will have to re-install your own applications and utilities..   

Windows 10 Pro - Start10 - part of a local network which is a '3rd party optimizer-free' zone..

Windows Update has nothing to do with upgrading a computer. Please post any future questions about installing or upgrading to Win8 here => http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_install
