web-platform-installer - 升级后 WPI 4.5 错误

Question

我刚刚在两台独立的 Windows 8 机器上将 Web 平台安装程序升级到 4.5 版。 (一个是物理机，另一个是虚拟机)。我无法运行 WPI 4.5，两者都显示以下相同的错误:

An error occurred while parsing EntityName. Line 42134, position 81.

更新:
确认这是 Microsoft 产品列表的错误。找到这个日志文件条目:

我真的很高兴谷歌向我指出了这个问题。在您发布此问题后 2 分钟，我收到了相同的错误...

这似乎是一个 Microsoft 服务器端错误，因为自从我开始输入这个答案以来，它已经为我纠正了。
