Installed directx 11 by mistake.

  1. Jul 31, 2010 #1
    I clicked download and run for directx11 without really thinking about it and now, daily, I've been trying different websites to get 9.0c installed back again and nothing seems to work.

    Ive done this about 10 times now...I find a website/mirror etc with 9.0c on it and download the damn thing. and then install it. I agree to the Eula ect and click install.

    Everytime I dxdiag my computer after rebooting it, it says that it is still running directx11!

    This is very frustrating.

    Is there a sure fire way to once again have 9.0c? (the only multimedia graphics and sound driver I have had any luck with?)

    My graphics card is a gt 250 Nvidia and I have some cheap creative labs sound card.

    Direct11 makes all videos I play choppy and the graphics get pixelated and hiccup so I hate it.

    Oh btw I did this scenario with directx 10 and was able to get 9.0c back again from 10.. I've gone back and forth between 10 and 9 many times without any problem... Directx11 seems to not ever let you change back again or I am doing something wrong?

    Is there ANY chance a Restore Point exists before you did this and it might possibly put it back for you? Or you happen to have an existing Restore Point you could use?

    Google for
    +directx +"Restore Point"
    finds hits that say "make sure you create a Restore Point before upgrading directx", some even from what appear to be Microsoft support. I hope it works out for you.

    Is windows update installing Dx11 automatically?

    I didn't even know you could install DX11 by itself, I thought it just came with W7.

    DX11 should work perfectly fine with your GT250 and sound card. I run an old Audigy sound blaster in my comp and it loves DX11. Make sure you mobo chipset is up to date.

    As for uninstalling it, I believe you just go to windows components list in the control panel and just tell it to uninstall.
