HTTP 错误 500.50 - URL 重写模块错误 - Microsoft.Web.Iis.Rewrite.Providers

我的电脑上出现此错误。尝试在 IIS Express 上从 Visual Studio 2015 运行应用程序。但本地 IIS 上也是如此。

HTTP Error 500.50 - URL Rewrite Module Error.
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Web.Iis.Rewrite.Providers, Version=7.1.761.0, Culture=neutral, PublicKeyToken=0545b0627da60a5f' or one of its dependencies. The system cannot find the file specified.

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. 
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

我安装了 URL 重写扩展，但我不认为我的 web.config 中有错误，因为它在我的笔记本上有效。 Windows 10、IIS 7、Visual Studio 2015。

这是我的 web.config 的一部分

UPDATE

我发现我的计算机上没有安装该程序集。但另一方面却是这样。如何下载/复制程序集？

UPDATE

问题就这样解决了如何从 GAC 中提取程序集？ https://stackoverflow.com/questions/714907/how-to-extract-an-assembly-from-the-gac从其他计算机复​​制程序集并重新启动。
