Cannot Play The Sims 2 Apartment Life - DirectX 9 error

Whenever I try to play The Sims 2 Apartment life, I get this error message:

Failed to enumerate any DirectX 9 compatible graphics adapters in this system!

Please make sure you have a DirectX 9 compatible graphics adapter and have installed the lates manufacturer provided driver.

The application will now terminate...
