Description

The page Install the .NET Framework 3.5 on Windows 11, Windows 10, Windows 8.1, and Windows 8 (code) proposes to install .NET Framework 3.5 via offline installer of .NET Framework 3.5 SP1.
This approach just doesn't work on Windows 8.1 64-bit (and probably other affected systems, where .NET Framework 3.5 isn't available initially) - the offline installer of .NET Framework 3.5 SP1 requires installed .NET Framework 3.5.
So when you start dotnetfx35.exe (downloaded from the .NET Framework 3.5 SP1 Download page), it just shows the dialog
.

Classic microsoft experience. Download the whole windows ISO even on windows to install this with disabled windows killer (I mean windows updates). Its amazing how much problems they make just to copy some DLLs and edit some register values.

Found this working solution: https://github.com/abbodi1406/dotNetFx35W10
Magically win10 works on win11 too, because its just DLLs. Microsoft please stop killing software, just dont do anything and everything will be fine. Just dont touch software
