I'm trying to install .NET Core Windows Server Hosting bundle on Windows Server 2008 R2 hosting IIS, but the setup is failing. from the log, I believe it's trying to download packages, which it can't do in our secured environment. I then tried running it with the /layout option, but the install runs for only a few seconds, says the setup was successful, but no packages are downloaded.
Is this installer self contained or is it trying to download additional packages and, if so, how can I run it with the /layout option?
