Question

我正在使用Windbg调试主线程callstack上有mfc140.dll版本14.0.24212.0的转储。由于某种原因，它无法下载此版本的mfc140。

以下是sym noisy的日志：

Answer 1

如果旧文件不在公共pdb服务器中，则没人可以说出实际情况。这可能是构建系统配置的错误。或这些时代的政策。或者它已经被删除了。

对于这种情况，我只建议更新可重新分发给the latest version的内容。 MFC140.dll具有与VS2015，VS2017和VS2019相同的接口。

Answer 2

我正在总结评论，已经给出的答案以及我的观察结果。

Microsoft符号服务器无法提供MFC / CRT的某些DLL。

.pdb文件在那里。

通过以下方式获取DLL

Installing proper C Runtime。请注意，您可能需要卸载更高版本的C运行时，还请注意，VS2015 / VS2017 / VS2019的C运行时是共享的。
从not official source下载DLL

mfc140.dll版本14.0.24212.0未从microsoft符号服务器下载
