Most stronger program don't see the win, but Kingsrow with MTC database see the win, Flits also. But with the normal 8egdb Kingsrow don't see it.
When you say "see the win", I don't think you mean "sees that the position is a black win". Kingsrow can see that this is a black win. What you mean is the the program cannot finish the game against a perfect opponent without a DTW or MTC/DTC database. The reason is that (if white to move, you didn't say) there are 42 plies to the next conversion (non-reversible move). Most programs cannot search that far ahead with so many kings on the board, so they do not know how to make progress toward the win.
Flits cannot finish the win against an MTC db. Set flits to play black, kingsrow with MTC db to play white. You will see that flits does not know how to win.
