See if this helps (both copied and pasted from the EA tiger woods 08 forum)

-The EULA for DirectX can appear blank on some PC configurations. IF this

a command prompt and type in " autorun.exe DXInstalled " to bypass DirectX
installation.
Or, as I saw elsewhere, someone downloaded DX9 and installed it, only
installing files from dx9 that wasn't in dx10 (apparantley)
