FAILURE

I'm starting from Map Manager, console, dev, window, and screenshot enabled, with a custom (Delta Ruined) UI, running on 1.08. I press the "Start Halo" button and almost immediately get the message

This application has failed to start because d3dx9_37.dll was not found. Re-installing the application may fix this problem.

I close that message and recieve Halo's error popup.

We are sorry, but you need to have DirectX 9.0b installed to run this program. Please run Halo PC setup again to install DirectX.

The same happens when I just double-click haloce.exe.

EDIT: Looks like I'm not the only one.
