PerfView - 当文件已存在时无法创建该文件。 （HRESULT 异常：0x800700B7）
PerfView - Cannot create a file when that file already exists. (Exception from HRESULT: 0x800700B7)
当我尝试使用 PerfView v1.9.0.0（收集 -> 收集 -> 开始收集，使用默认参数）创建 ETL 文件时，操作失败并显示“出现异常情况，详情见日志"
下面是我在日志中看到的内容：

当然，文件 从不 之前存在并且 不存在 在（失败的）操作之后也存在。每次我尝试收集时都会发生这种情况，无论我提供的文件名或目录如何。
我做错了什么？
谢谢magicandre1981 for your suggestion. I am indeed using Windows 7 and I was running Process Hacker。在停止 Process Hacker 后，PerfView 能够成功执行收集。干杯。
直到 Windows 7，您只能使用一个名为 NT Kernel Logger 的内核会话。从 Windows 8 开始，您可以使用不同的名称创建新会话。
On Windows 8, Windows Server 2012, and later, the SystemTraceProvider
can be multiplexed for up to 8 logger sessions. The first two slots
for logger sessions are reserved for the NT Kernel Logger and the
Circular Kernel Context Logger .
因此请停止使用 NT Kernel Logger 的工具（例如 Process Explorer、Process Hacker、Resmon）来解决问题。
