我正在IIS服务器上工作，并通过创建新的站点添加公共文件夹（Laravel项目）作为物理目录在IIS服务器中部署Laravel项目。我有错误，如

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

我有this.so错误我下载了url rewrite并安装了它的工作。现在我的观点是，如果我下载并运行意味着它会影响当前运行的位置也？例如，我正在运行5个sties在IIS和第6个站点有错误，我下载和运行它会影响的退出站点也？.或者直接更改web.config？

只是简单的，如果我下载并运行重写网址。它会影响现有的网站？.或任何更改需要在web.config？
