推荐答案

引用：

搜索...按VID

当谈到供应商ID（VID）时，Windows Management Instrumentation（WMI）会参与其中。 WMI经常被破坏。

因此我建议在显示例外的计算机上修复WMI.Google / Bing等将帮助您找到该程序的步骤。

When it comes to the Vendor ID (VID), Windows Management Instrumentation (WMI) uses to be involved. And it does happen rather often that WMI is corrupt.
Hence I suggest to repair WMI on the computers showing an exception. Google/Bing etc. will help you find out the steps for that procedure.
