downloaded the directx 9c installation files for third party vendors to bundle with their software. As I couldn't get the web installer to work. It installed fine dxdiag even runs. In the files section it is missing;
Direct draw and direct 3D work just fine. I have installed Age of Empires II and I can't seem to get it to work. So still troubleshooting that.
ddrawex.dll is, even if it sounds strange, a part of Internet Explorer.
The files section will show strange stuff like non-microsoft files. CrossOver reimplements DirectX on top of OpenGL and other Mac/Linux equivalents like Alsa or CoreAudio. The logical consequence of this is that dxdiag can complain about non-Microsoft DirectX files.
Installing DirectX is not necessary with many apps. It helps if the application uses high level helper libraries like d3dx9 or DirectPlay. You cannot use the DirectDraw or Direct3D part from the Microsoft DX runtime because there is no Windows kernel or Direct3D driver running. CrossOver will refuse to use Microsoft's ddraw.dll or d3d9.dll.
(Age of Empires 2 however, uses DirectPlay, so the dx runtime helps with multiplayer games)
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
