I just verified with wine 0.9.43 and the problem is still there.

The hex hack I did disables the message box that displays "ScreenStack ::
realize(): BitBlt 2" and aborts installer. Look below at the snippet of the
code - first BitBlt is executed, then eax is tested against value of 0; if it
is 0, then the error box is displayed; my hack replaces "jnz" with
unconditional jump ("jmp").
                call    ds:BitBlt
                pop     edi
                pop     ebx
                test    eax, eax
                jnz     short loc_411335
                push    offset aScreenstackR_0 ; "ScreenStack :: realize():
BitBlt 2"
