Problema di dx non riesco ad installarle!!

[stopper11]

ciao a tutti ho il seguente problema ho scaricato la beta di bf3 e quando provo a installarla mi dice
error a redistibutable package(directx) was not installed successfully
setup cannot continue.(-9)
quindi dico vabbe devo intallare le dx quindi lancio il setup altro errore
si è verificato un errore interno di sistema.
per individuare il problema vedere i file dxerror.log e directx.log nella cartella windows.
vado a vedere questi file e mi da questo codice
