Biab has a checkbox to acidize a loop or not. Biab by itself does not require a loop to be acidized so the answer would be the good ole "it depends".

I also picked up Acid Pro 7 a few years ago off Ebay for cheap and like you I found very little online explaining how to use it. Just now I googled it again and all I find is some users wishing Sony would update it, issue patches, etc and so far no official comment about it. It appears dead for now so if you want to use it you're on you're own.
