If I try to launch any game from steam, it gives this error:

Steam - latest DirectX required
The latest version of MicrosoftX(r) is required to play [game] Microsoft DirectX(r) download site

However, I can still launch games outside of steam with the executable if that particular game allows you to (not all of them do, or some don't work properly.) This leads me to believe this error has nothing to do with DirectX 9.0c being installed, but something to do with the registry or incompetence on Valve's part.

This error is new as well, everything used to work fine. Tt's been happening for a month or so. I do not remember what I could have done that would cause this. I haven't messed with DirectX at all. I've looked at every search result I could find in regards to this error, but none of the solutions have helped.

The link in the error redirects to a page begging you to download windows 10 (guessing this is their way of saying Page Not Found.) I found the "improved" link to the download at https://www.microsoft.com/en-us/download/details.aspx?id=35&44F86079-8679-400C-BFF2-9CA5F2BCBDFC=1

As with Microsoft, installing fails with:

DirectX Setup: An internal system error occured. Please refer to DXError.log and DirectX.log in your Windows folder to determine problem.

But those two files are not in the windows folder.

Here's what I've tried (in no particular order):

  • Reinstalling Steam
  • Reinstalling some games in case it would download the needed DirectX
  • Reinstalling the graphics card driver
  • Reinstalling update KB2670838
  • Reinstalling, from the control panel, everything related to .NET, C++, and Visual Studio
  • Running the DirectX install as Administrator
  • Using the "DirectX End-User Runtimes (June 2010)" installer instead
  • Running them with steam closed
  • Running them with anti-virus closed
  • Running them in safe mode
  • Running sfc /scannow
  • Running CCleaner on the registry
  • Launching game with /dx9 or /dx11
  • Adding this to the registry:

    Windows Registry Editor Version 5.00

  • It happens with every game except a couple old ones Jan 3, 2016 at 3:38
  • It'll likely be hard to find, but what's causing the problem is probably mentioned in one of the DXError.log and DirectX.log log files. My guess is something is preventing the installation of one or more of the d3dx*.dll files or other optional redistributable DirectX DLLs that aren't included with Windows 7.

I've had cases where installing an older game forces an installation of a particular version of DirectX, and somehow the compatibility is broken. It seems to report version N, but really some parts of it are an earlier version. I recommend removing DirectX entirely and reinstalling the whole thing. You could just try to install the current version without removing anything, but that leaves open the possibility of conflict again.

So far, the times I've had that with Steam games (and other non-steam games) removing/reinstalling DirectX has resolved the issue.

EDIT: One of the things I didn't mention before was the fact that Steam provides a bit of a "contained installation" of games. If there are particular things that a game needs (Dosbox is a good example) then Steam will handle that for you. While it's entirely possible for you to run some games outside of Steam, they are really not designed to do that. Steam manages things like DirectX installations for a game, preventing it from quashing the one that you have on your computer. Some games use Windows Live, some games use UPlay, and Steam manages that for you. I'd highly recommend not launching games outside of Steam if you can manage it.


This is not a permanent solution, but a workaround for source engine games I found from here: http://forums.steampowered.com/forums/showthread.php?t=2460057 (I'm the original poster, lost the account)

1. Open your root CSS folder
2. Create steam_appid.txt and write "240" (without quotes) in it
3. Launch hl2.exe with these options:
-game cstrike -console -steam -secure

However, the problem remains with some games such as Don't Starve Together Beta which go through steam first and run into the DirectX wall. I'll see if there's any way to fix whatever registry calls are causing this error. And if that doesn't work, I'll try to get the games to launch without that steam DirectX check.
