Visual Studio Tooling - Error Installing .NET Core 1.0.1

I'm trying work with .NET core on a Virtual Machine that is blocked from downloading any content from the internet. It appears that the installer DotNetCore.1.0.1-VS2015Tools.Preview2.0.3.exe requires an iis express package that it cannot download. The package is from:

https://download.microsoft.com/download/F/6/E/F6ECBBCC-B02F-424E-8E03-D47E9FA631B7/packages/ancm_iis_express_x64_en_69.msi

I can download this package manually and install it, but the VS2015 tooling installer still fails. I'm guessing that it uninstalls all ASP first, then re installs this package. (Previous step is "Preparation_Uninstall_ASPNET")

Any ideas on how to work-around this problem?

Here is an abbreviated version of the installer log:

Please note that the VM has no internet access to make the download request.

Thanks, and sorry for the long error log.

Found this somewhat cryptic, but correct answer: Dot net core 1 Tooling Preview offline installer

You can create an offline installer by following the instructions here from MSDN: https://msdn.microsoft.com/en-us/library/mt706497.aspx

This uses the /layout option to force the download of all packages. (This can be very large!) These can be copied over as an offline installer.

Note that this technique should be good for other MS installers as well.
