I have gotten conflicting information on this subject. There are a lot of techies out there saying that you cant go from Windows 7 32 bit to Windows 8 64 bit. If I don't download Windows 8, but order the DVD set. Can I install Windows 8 64 bit directly? Seems like many techies think that you have to install Windows 7 64 bit first... this seems like wasted time and money for someone that would have to buy the 64 bit version of Windows 7... please help!

If you want to Upgrade from Windows 7 32-bit to Windows 8 64-bit you will have to go via either Windows 7 64-bit, or Windows 8 32-bit, the latter one presumably being included in the same Box as Windows 8 64-bit.

No you can't go from 32 to 64 unless you make some major changes. 1) If you don't have AT LEAST 4GB or RAM, I don't recommend you run 64 bit Windows at all. 2) Your processor must be able to handle the 64 bit OS. Some processors can't. Keep those in mind.

For some reason, Microsoft doesn't allow you to upgrade Windows 7 (32 bit) to Windows 8 (64 bit).
The Windows 8 Upgrade Advisor will only allow you to go from 32 bit to 32 bit, or 64 bit to 64 bit.
'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, but you'll need to buy Windows 8 as a DVD.
You also won't be able to keep any files, settings, or apps when you upgrade from a 32-bit to a 64-bit version.
I have no idea why they made this a requirement... It looks like they want to to spend the extra $30 to upgrade to a 64bit version. (Which I highly recommend you do since you have 16 gigs of RAM in your machine.)
You can legally download a free copy of Windows 7 from here...
These versions will work for 30 days until you activate them. In theory, your 32 bit key will work on a 64 bit version of Windows 7 as well, giving you a legal copy of Windows 7 64bit. You can then upgrade to Windows 8 64 bit.
NOTE: Windows 8 is not a great Desktop OS. It BEGS to be used on a touchscreen. Really think twice before making the upgrade. I don't recommend anyone upgrade to Windows 8 if they don't have a good reason.
WARNING: When you install a 64 bit OS over a 32 bit OS, YOU HAVE TO PREFORM A CLEAN INSTALL! MAke sure all of your data is backed up and safe before proceeding.
