1. Regardless of whether the operating system is Windows Server 2022 Standard or Windows Server 2019 Standard, the Windows service component OpcUaServerWinCC still cannot start and run after installing the latest WINCC V 8.0 UP 4 software and having a legitimate WinCC Connectivity Pack license. 2. After installing the latest WINCC V 8.0 UP4 software, install the OpcUaServerWinCC package in the standard way or the custom way, or uninstalling the OpcUaServerWinCC plug-in package separately, and then restart the computer to install the OpcUaServerWinCC plug-in package, the Windows service component OpcUaServerWinCC cannot start and run. When starting the OpcUaServerWinCC service, a fault of 0X80004005 is reported. 3. When OpcUaServerWinCC is tested under WINCC V 7.5 SP 2 software, Windows service can start normally, but OpcUaServerWinCC service cannot be run after installing WINCC V8.0 UP 4. Please help to figure it out. thanks
