SXPG_COMMAND_EXECUTE Can't exec external program (No such file or directory

Question

Hi Experts,
I need to launch or terminate an external application (i.e. command prompt, notepad, etc.) in background job by using FM SXPG_COMMAND_EXECUTE. However, I am unable to proceed because of the following error occured after executing the command in SM69.
Can't exec external program (No such file or directory)
External program terminated with exit code 1
I was using the following sample code. Can someone tell me what might be the cause of the problem?
DATA: lv_status TYPE extcmdexex-status,
      lt_output TYPE TABLE OF btcxpm,
      lv_opsys  TYPE sy-opsys.
lv_opsys = 'WINDOWS NT'.
CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
  EXPORTING
    commandname                   = 'ZIEXPLORE'
    additional_parameters         = '/c'
    operatingsystem               = lv_opsys
  IMPORTING
    status                        = lv_status
  TABLES
    exec_protocol                 = lt_output
  EXCEPTIONS
    no_permission                 = 1
    command_not_found             = 2
    parameters_too_long           = 3
    security_risk                 = 4
    wrong_check_call_interface    = 5
    program_start_error           = 6
    program_termination_error     = 7
    x_error                       = 8
    parameter_expected            = 9
    too_many_parameters           = 10
    illegal_command               = 11
    wrong_asynchronous_parameters = 12
    cant_enq_tbtco_entry          = 13
    jobcount_generation_error     = 14
    OTHERS                        = 15.

Hi Louie,
I am not able to assume the reason of the problem, If you say that its not getting executed in SM49 then the problem lies there.
So I am providing you a link which might be helpful, just go through it and cross check. There is a parameter called "trace" in the fm mentioned.
