If you have 64-bit clients, OpenOPC will also fail as well. However, I do not see QuickOPC in the list of classes supported by OpenOPC. > In my Case pywin32 is not matching with the version python I’m using . Why do you think so? You have Python 3.8, and the Pywin32 is for Python 3.8. If there were a mismatch, you couldn’t call Dispatch at all. > Can you please suggest me the versions which I can use to solve this errors , because the same version I’m using in another windows laptop there I’m not getting this errors. Either something has gone wrong with your QuickOPC installation, or you need the 64-bit Python. — Tim Roberts, [email protected] Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list [email protected] https://mail.python.org/mailman/listinfo/python-win32
