I've added a program which lets you change version easily for BW, in case anyone wants to do runs on older versions.

It only works for BW and not SC:R. If you have only SC:R installed, I think you can copy the SC:R installation folder and then turn off Express Mode in SCV Selector and choose the copied folder manually to have both SC:R and BW with older versions installed. I can't test this right now but I'll be able to confirm it later.

EDIT: Confirmed to work on a copied folder, which is useful for having multiple versions of BW installed at the same time.
