Unable to create direct3d9 device

When I run MoI I get the message "Unable to create direct3d9 device" in all four viewports. I downloaded "directx_jun2007_redist.exe" unpacked it to a folder and ran the install program, which did not report any problems. MoI still gives the "Unable to create direct3d9 device" message. What should I try next?
