Yes - but only if you've been running a 64bit version already

Microsoft do make it clear themselves http://windows.microsoft.com/en-US/w...e-to-windows-8

Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows 8?

Yes, but you can't do this using Upgrade Assistant. If your PC has a 64-bit capable processor (CPU) but is currently running a 32-bit version of Windows, you can install a 64-bit version of Windows 8 Pro, but you'll need to buy it as a DVD and perform a custom installation. If available in your country or region, you can buy Windows 8 Pro from a participating retail store. You can also buy it online from the Microsoft Store in Austria, Belgium, Canada, France, Germany, Ireland, Italy, Japan, Netherlands, Spain, Switzerland, United Kingdom, and United States.

Please note that the Windows 8 Pro Pack is used to upgrade from Windows 8 to Windows 8 Pro, and is not for cross-architecture installs and does not include any media. If you want to change architectures, purchase Windows 8 Pro.

You won't be able to keep any files, settings, or apps when you upgrade from a 32-bit to a 64-bit version.
