您好jenkstom，

根据到错误消息，Workload.NetCrossPlat和Xamarin.Inspector包无法下载，无法正确安装。
从您的描述中，听起来像那你已经尝试了很多步骤但仍然没有帮助，我建议你参考

这是我的布局VS 2017文件夹，其中包含所有Xamarin包：
离线安装程序完成后，您可以运行vs setup.exe来执行顺利安装。

Hi jenkstom,
Thank you for posting in MSDN forum.
According to the error message, Workload.NetCrossPlat and Xamarin.Inspector packages failed to download and couldn't install correctly.
From your description, sounds like that you have tried so many steps but still no help, I suggest you refer to Create an offline installer for Visual Studio 2017 to make an offline installer, it allows you to download full resources of VS2017.
Here is my layout VS 2017 file folder, which includes all the Xamarin packages:
After the offline installer is complete, you could run the vs setup.exe to perform a smooth installation.
Best Regards,
