You have 2 problems.
You have identified one, you cannot mix 32 and 64 bit Office installations.
Your Office license gives you the right to install either 32 or 64 bit versions. MS defaults to 32 bit, which is giving you a problem.
Office 2016/365 requires you provide an email account at the start of the install process. Have you gotten past that point?
If you have Log in to the MyAccount site, it should show your 2016 H&B license. If it does, then you can use the instructions for finding the "offline installer" to find your 64 bit installation option.

How do I use the Office 2016 offline installer for Office 365?
If you made a one-time purchase of Office 2013 or Office 2016 (not a subscription to Office 365), you can download the install files directly to your computer.
Important Downloading the install files can take quite a while. Please be sure your computer stays powered on and connected to the Internet while downloading.
Sign in to your My Account page.
Choose Install from a disc.
Choose I want to burn a disc, and then choose Download.
Save the installation file to your computer and then run it to install Office.
**Applies To:**Office 2013, Office 2016
I suspect you have another problem that you haven't encountered yet. I SUSPECT that you will find that you CANNOT install 2016 H&B alongside Visio and Project. I SUSPECT that MS has built in a bias against "Home" users and Visio/Project. I hope I'm wrong.
(Please let us know if you do successfully make this installation so I can confirm/deny my suspicion). If that happens, one option is to install one of the products inside of a VM like Hyper-V or VirtualBox. That should isolate the installations enough
to allow them to complete.
