    Did you download the installer directly from Microsoft's website? I think this problem relates to anti-virus software, if you have it disable it and then try to run the installer. Also if you didn't try it already, maybe a reboot would help.

    No, it has to do with the installer using a old or expired Certificate. The new Windows 8 probably uses a different chain or root certificates. You can try downloading and installing the root certificate for that particular Installer.

    Majority of people get their certficates from Symantec (Formerly Verisign).

    Licensing and Use of Root Certificates | Symantec

    Download the VeriSign Root Package and install all the certificates in each folder.

    The other thing is download the directx Installer from Microsoft:
    Download DirectX End-User Runtime Web Installer from Official Microsoft Download Center

Some of the games I have seen have the options to select which one to use, dx9 or 10 or 11. Honestly, I have just a little approximate knowledge of what these do most of them from experience. - dx9 runs smoother (just for me i suppose) - dx10 just adds shinys and i did not really use it....
DirectX is giving me problems.
I am beyond the veil of anger with this. I believe something is wrong with my DirectX 11 on Windows 8.1, and I don't know how to fix it. I would go to play certain games, and it would pop up an error message saying "Cannot Set Display Mode" or something similar to that. I get the feeling it's...

So what do you expect from a possible directx 12 release? I personally hope for ray tracing support.
