安装wincc碰到问题
MS Security Patch is not installed on this system.
For this WinCC Version, the following software is required:
WindowsXP SP 2 KB319740
Please run the installation of MS-Security Patch from your MS Tools - CD.

Operation of WinCC under Windows XP SP2 has been released for WinCC clients with deactivated firewall only.

You must deactivate the firewall manually
微软网站好像找不到这个(Q319740)补丁。。。
请各位帮忙啊
