Well, answer is in your quiestion: This program requires Microsoft Windows.
DOS is not Windows. So no support under "pure" DOSBox.
But! "Win" signifies that it's "old" Windows. 3.x, namely. And, unlike "Win as OS" (that is Win95 and newer), "Win as shell" is quite possible under DOSBox!
Check
this thread to find Win 3.x and it's setup for DOSBox.
