Visual Studio 2017 fails to install offline with “Unable to download installation files”

Question

So I\'ve created an offline installed of VS 2017 Community on my laptop using this command:

vs_community.exe --layout \"D:\\Downloads\\VS

Answer 1

Was doing this for VS Community 2017 and it would install everything and it does the core installation without any trouble. However, if i select to install the universal or .Net development portions it will install it almost completely, but it will fail on two files. It will say that it cannot download the files from the internet. The files exist in the installation directory and I even went and downloaded the files and placed them into the appropriate directories and it still thinks that it needs to download those two files preventing me from completing the installation process. If I just continue it will install everything else except those two files. I've tried this with a few different layout downloads in different forms (ISO, directory, etc) and same issue (so it isn't a bad download or anything, and I'm sure I did that all correctly). The two files are:

https://download.visualstudio.microsoft.com/download/pr/10983757/f8c877406947fdc71ed2dd9127d2f9fa/microsoft.codeanalysis.visualstudio.interactivecomponents.resources.vsix

https://download.visualstudio.microsoft.com/download/pr/11347028/25bedee219940beceecab91dac231235/microsoft.visualstudio.testtools.testplatform.legacy.core.resources.vsix

If I plug myself online and do a repair it will go grab those two files without having to grab everything else, but it kind of defeats the purpose. Don't expect a solution, but wanted to mention it because all the other problems are related to installing the certs and I can't find anything online about it failing on just a few files.
