Clean and fresh windows install, unfortunately.
There's no option to 'upgrade' it.
When you enter the Windows menu to install, after formating, it will show you which version of the OS you'd like to install, there just choose 64 bits and wait the rest.
I'd do a fairly good backup of files and drivers to prevent any problem.
For an easier install, just go through these steps:
