Error with DualSPHysics3.4_LiquidSediment_win64


I installed FreeCad v0.19 and downloaded DualSPHysics 4.4.12 following the instructions in the manual. I‘d like to repeat the dam break test with moveable bed. Thus, I change the setup plugin adding the path to the DualSPHysics3.4_LiquidSediment_win64.  However, when I click on the execution parameters, I get this error:
