我在win10 系统中python 32位 ，管理员运行pycharm

代码1：fromctypes importWinDLL

importos

fromwin32com importclient

DmReg = WinDLL(r'D:\插件\大漠dll\dmReg.dll')

DmReg.SetDllPathW(r'D:\插件\大漠dll\dm.dll',0)dm = client.Dispatch('dm.dmsoft')

print(dm.ver())

代码2：

import ctypes

from comtypes.client import CreateObject

dms = ctypes.windll.LoadLibrary(r'dmReg.dll')

dms.SetDllPathW(r'dm.dll', 0)

dm = CreateObject('dm.dmsoft')

print(dm.Ver())

运行之后报错

D:\pythondaima\Gamewendao\venv\Scripts\python.exe D:/pythondaima/Gamewendao/lins.py

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch)

pywintypes.com_error: (-2147024890, '句柄无效。', None, None)

进程已结束，退出代码 1

上面两种代码运行之后错误差不多一样，都是句柄无效

希望有懂的大佬帮助一下，谢谢。
