So I am trying to install Sharepoint Server 2019 on a box with Windows Server 2016 that is not connected to the Internet.
You can see the software and hardware requirements here:
https://docs.microsoft.com/en-us/sharepoint/install/hardware-and-software-requirements-2019
Ok, so it requires Microsoft AppFabric 1.1 for Windows Server.
But apparently Microsoft AppFabric 1.1 can't be installed on Windows Server 2016: https://www.microsoft.com/en-us/download/details.aspx?id=27115 (Look at supported operating systems)
Wha...?
I downloaded WindowsServerAppFabricSetup_x64.exe from that link, and the installer wouldn't run. Is there some other link that I should download it from?
