调用pywinauto来启动.exe时报740

Question

-*- coding:utf-8 -*-

from pywinauto import application
from ctypes import *
app=application.Application.start("C:\Program Files (x86)****.exe")

错误代码如下

File "build\bdist.win32\egg\pywinauto\application.py", line 825, in __start
File "build\bdist.win32\egg\pywinauto\application.py", line 876, in start_
pywinauto.application.AppStartError: Could not create the process "C:\Program Files (x86)\FClassroom\Fclassroom\FClassroom.exe"
Error returned by CreateProcess: [Error 740]

740有说是权限问题，我把程序属性勾上管理员运行也还是不行，求解
