I don't think you're asking the right question. BIAB 2019 comes with both 32-bit and 64-bit versions, and both are installed at the same time. The additional files for 64-bit are relatively small.

But if you have a 32-bit version of Windows, you won't be able to run any 64-bit software programs. You will, of course, be able to run BIAB 2019 32-bit just fine.

We can talk more about what your next step might be. First, find out if your computer has a 64-bit processor (CPU). You should be able to see this in Control Panel, System.
