Microsoft distributes DirectX exclusively through Windows Update.

Note: Version 102902 is a DirectX 9 component. Windows 10 and 11 include DirectX 12 and 11 by default, but they do not include all legacy DirectX 9 files. For some old games, you must manually install the June 2010 redistributable.

Yes. Windows 11 does not include DirectX 9 by default. You must install the DirectX 9.0c End-User Runtimes. The 102902 build functions perfectly under Windows 11’s WOW64 layer.
