Answer 1

就像Chlebta说的；尝试直接下载文件。

我已将 URL 更新为最新版本： http://download.xamarin.com/MonoforAndroid/Windows/mono-android-4.8.00013.msi

Answer 2

我刚刚第二次遇到同样的问题。

以下是允许我解决它的步骤：

1. 卸载所有 Xamarin 产品（Xamarin Android、Xamarin Studio 等）
2. 转到 C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions 并删除 Xamarin 文件夹
3. 转到 C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions 并删除 Xamarin 文件夹
4. 根据需要安装 Xamarin Studio 或 mono-android-4.8.00013.msi

我希望它会有所帮助（并希望问题不会再次发生......）

Answer 3

MSI 未完成：从 URI http://download.xamarin.com/studio/Windows/XamarinStudio-5.0.0.878-0.msi 直接下载时（7,627,523 字节）与（40,300,544 字节）
