The installation experience of SharePoint 2019 to Windows Server 2019 was brisk except that I have issue during pre-requisites installation. It takes me sometimes before I realize that SharePoint 2019 still require Windows features that depends on .NET Framework 3.5.
I launched prerequisites installer, and it stops quickly with error.
I click “Review the log file” in the error window, then it opens the log file in Notepad.
As you can see, that prerequisites installer executes Install-WindowsFeature. Then, I open PowerShell command as Administrator and run the command in the PowerShell. And as expected it failed, but there is hint that Net-HTTP-Activation and Net-Non-HTTP-Activ requires .NET Framework 3.5 Features.
.NET Framework 3.5 is not installed by default in Windows 2019. Then I search if the package is available in the installer folder.
I run the original command and adding -source , parameter
After adding -source parameter the command completed successfully. Then I rerun prerequisites installer again successfully.
