【问题描述】:
我在特定的 window 8.1 操作系统中遇到了这个问题。这在 Window 7 和 Window 10 中运行良好。在此问题窗口 8.1 操作系统出现 WMI 损坏问题之前,我已修复此 WMI 服务,我的其他服务运行良好,但突然出现错误。 这是因为 WMI 被修复了吗? 错误:
2017-08-08 10:41:23,856 [12] ERROR ERDeviceControl.WACardioPerfectControl.WACardioPerfectControlClass [(null)] - Error while invoking _RunTest in

【问题讨论】:
-
8 == 致命错误,7 == Windows 错误代码,0x2e4 == 740 == ERROR_ELEVATION_REQUIRED,“请求的操作需要提升”。那takes you here.
