A few added thoughts.

When BIAB 2018 was first released, the older PG Music plugins were only available in 32-bit. But they released 64-bit versions, so there shouldn't be any difference.

A 64-bit app can address more memory, and use all available memory in a PC beyond 3.1 GB, but that limit was solved with the JBridge utility as Bob mentioned.

Use whichever you prefer, as long as your Windows is 64-bit. If it's a 32-bit operating system (use Control Panel, System to check), you would be limited to the 32-bit version of BIAB anyway.
