The screenshot says "OSError: [WinError 87] Falscher Parameter" at Lib/subprocess.py:1178 which is this call: hp, ht, pid, tid = _winapi.CreateProcess(executable, args, # no special security None, None, int(not close_fds), creationflags, env, os.fspath(cwd) if cwd is not None else None, startupinfo) According to the traceback, the call is: subprocess.check_output([execStr,"-3",self.geofile,"-o",self.vtkFile]) Can you please dump these parameters? Are they all strings? IMHO execStr, self.geofile or self.vtkFile is not a valid string and it's a bug in your code.
