Hello,

Yes Band-in-a-Box and RealBand are 32bit threads and so any VST plugin running on the BBW.exe thread will need to be 32bit as well.

It is also possible you installed both versions of the plugin in different locations (they have an identical file names) and are perhaps now choosing the 64bit item when the 32bit version is available in a slightly different location.

You may just want to remove the plugin and re-install the 32bit version only, to a specifically convenient location.

Thanks,
Rob.
