Please note that if you download the 0.15.0 precompiled demos and want to run them using DirectX9, you will have to make sure you have the latest DirectX runtime (9.0c). That’s because the demos have been built against the very latest SDK version, and if you try to run them on a machine with a previous version of DirectX, you will get an error.
You can download the latest version of the DirectX runtime from the Microsoft DirectX page.
