when i attache the simulation file of PSIM in the simulink using simcoupler then it generates an error when i press apply button. Following is the error message:

Error using PSimDialog>CloseBtn_Callback (line 217) Error reported by S-function 'SimCoupler' in 'chop1q_ifb_simulink_r_13/chop1q_ifb_psim': PSIM Message: %1 is not a valid Win32 application.

Error in gui_mainfcn (line 95) feval(varargin{:});

Error in PSimDialog (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)PSimDialog('CloseBtn_Callback',hObject,eventdata,guidata(hObject))

Please guide me with error gerated by Matlab. Thanks
