i can't update my directx, it always 9.0

hello all, i using win 7 ultimate x86 and ati radeon hd 4650
i can't update my directx, everytime i do it, it always finish and show 9.0
is there something wrong or my vga didn't support it ?
thanks for any help

thanks to respond
sorry, i usually scan with siw.exe
it always said 9.0
when using dxdiag it show 11
which one is the right one ?

Looks like SIW is in severe need of an update as it shows the same for 4830, which just like your 4650 is a DirectX 10.1 card. Also in dxdiag look under the Display 1 or Display 2 tab, and under Drivers the DDI version should be showing as 10.1.

Windows by default has DirectX 11, your VGA card might not support the latest in terms of gaming. But yours appears to.

hmmm, my vga works for vista directx but not win 7, am i right
what should i do to change it to another DDR
i must change another hardware too ??
i see 5550 can handle directx 11

W7 is installed with DX 11 as part of OS. Only the very latest vid cards will even support DX 11. Most games do not support DX 11.
Many vid cards are DX 10 ready, as well as many games.
Mostly older vid cards support only DX 9.0c, 8.1. Majority of games support DX 9, 8.1.

Just buying a new vid card might not get you what you seem to intend, DX 11, usage.
DX is backward compatible so that part is covered. Many go ahead an install DX 9 on a W7 system because some games just require DX 9.
I could be wrong but you misunderstand how DX is deployed and whats its use.

FYI
