You are correct, the default installation loads the 32-bit version of BIAB 2019. But the 64-bit version is also already installed. One way you can load it is create your own Windows shortcut. The file you want in your /BB folder is bbw64.exe (not bbw.exe). Make a shortcut of this file and while you're there, set it to Run as Administrator.

Note: if you haven't created a shortcut in Windows before, just right-click on an empty area of your Windows desktop. You'll see the option to create a shortcut under New, Shortcut.

You probably already have a shortcut from your older version of BIAB that goes to bbw.exe which will now load the new 32-bit version. So you'll have two similar-looking shortcuts.

Let me know if any of that explanation is confusing.
