Install .NET 3.5 on Windows Server 2016 for Biztalk

Why would Windows Server 2016 need .NET 3.5? Well, ask Microsoft as it is needed for Biztalk 2016, a product that also requires an old SQL Server version (will not install on 2017) with Windows authentication. Anyway, put that aside. We need it and it should be a simple thing to add the feature. Unfortunately it is not. The wizard complains that it can’t find the files.

After some digging I managed to get it to work. First of all, open the group policy editor (gpedit). Navigate to Local Computer Policy -> Computer Configuration -> Administrative templates -> System -> Specify settings for optional component installation and component repair. Change the option to Enabled with “Download repair content…” on. Exit the application and run in a command prompt as administrator:

dism /online /enable-feature /featurename:NetFX3 /all /LimitAccess

Hopefully that should do the job. Phew!
