Yes - the installer for DirectX
. DirectX (or rather, it's Direct 3D part) is updated every few months and usually each update comes with a new on of those D3DX9-DLLs. If a program depends on a newer DLL than you have installed, you'll get this error. (And no, Windows 7 didn't exactly ship with the newest Direct 3D DLLs - and DirectX isn't distributed via Windows Update either...)
Though when you run the ToMI setup the game asks if you want to run the DirectX installer - did you answer no to that question? Because otherwise I can't see how you wouldn't have the latest DirectX version installed...
np: Vladislav Delay - Tummaa (Tummaa)
