I plug and play fails only getting driver for this maker, will work.
are you in the UK,,, we are USA< and when I google that maker it lands UK , why? IDK.
the A79LH , is that you model not stated?
is it USB connected? If not say what?
not is one old and rare scanner my guess over 10 years old.
and w10 does go beyond that for sure if maker stops support and their web page has zero legacy support.
there are generic scanner software apps you can buy and might work.

I would try to contact the maker, find them and contact them.
