Impossible d'installer directX 11

Bonjour,

Apparemment, lorsque je lance un jeu sur steam il me dit qu'il me faut la dernière version de directX ( je suis sous windows 7). Alors je vais dl l'installateur :
http://www.microsoft.com/fr-ch/download/details.aspx?id=35
Puis quand je tente de l'installé il me sort un message d'erreur :
"Une erreur système interne s'est produite. Consultez les fichiers DXError.log et DirectX.log pour déterminer le problème.".

Le DXError.log est :

Bref que de confusion dans ma personne maintenant donc si quelqu'un pourrait m'aider ça serait franchement cool, de plus oui je sais que le sujet à pas mal été traité mais cependant aucune des solutions que j'ai testé n'a marcher.

Merci d'avance
