Directx 9 in Windows Vista

Hello. Is it necessary to install Directx 9 in Windows Vista ? On Microsoft website, at Directx 9 operating system requirements appears Vista. But I know that Vista includes Directx 10. So, neet to install Directx 9 ?

 

Vista needs both, DX9 and DX10. The updates include usually both versions.

 

It does.

 

thats correct, because lots of games made for dx9 required random files from dx9 update to run proper in vista or xp, and the same thing is for dx10

 

So, finally, must I install Directx 9 Runtime in Windows Vista ?

 

It's already installed, it uses both.

 

I know, but for example Rainbow Six Vegas, after instalation updates Directx 9 Runtime . I knew that Directx 9 is installed, but what updates did Vegas ?
On Microsoft Website is an update of Directx 9 for Vista :

So, update is necesarry ?

 

just download the latest dx runtime from the website

 

Could have been any one of the d3dx9 dll's that got updated (in my System32 folder i have 12 of them numbered from 24 to 35), or if you were missing one of those dll's it got added; or amy number of other DX 9 files that got updated.



Also check the dates on them. Just because some of them are older, doesn't mean they don't still get updated occasionally.

 

Stormy, thanks' for reply. I've noticed that I haven't installed d3dx9_33 , d3dx9_34 and d3dx9_35 .dll. How did you obtain these files ?

 

Download the whole thing (58.8 MB),

http://www.microsoft.com/downloads/...f3-0949-487b-9247-8fee451bf952&displaylang=en

run it and it will update what is needed. Or download the websetup,

http://www.microsoft.com/downloads/...38-DB71-4C1B-BC6A-9B6652CD92A3&displaylang=en

and it only downloads and installs the bits needed (44 KB - 44.7 MB). Last time I ran this one it downloaded and installed a whopping 2.5 mb worth of files.

It will install/update all DX 9 files as well as DX 10 (Vista only), both audio and video.
