I went and asked Google all about it and it turns out that Microsoft does not allow different installers to be used at the same time. Well, no it wasn’t, it was 64 bit and I was installing a 64 bit version of Visio. When I ran the install, I received an error that Office 365 was not 32 bit. Well it turns out that Visio Pro 2016 standalone is installed by Microsoft Installer. I then wanted to install a standalone version of Visio Pro 2016 which I had an ISO image and key (NOT A SUBSCRIPTION).

I had Office 365 ProPlus Subscription (Click-to-Run) installed on my Windows 10 computer. I am not going to try and add a lot of fluff, this is the Cliff Notes version of getting Visio Standalone installed along with Microsoft Office 365 ProPlus.
