Even though BiaB is not running the folder locations do matter. You may be trying to add a VSTi to the wrong type of track.

try this:

Open reaper to the tracks view

right click to the left of the tracks area under the transport area (blank area) chose "Insert virtual instrument on new track..."

chose "VSTi3" Band in a Box DAW VST3 Plugin (PG Music Inc.) (16 out)

Say either yes or no to the 16 output option ( i usually say no) i just want a stereo output set up.

Let us know what happens.
