windows8.1 disables part of DirectX control panel?

I did find some posts referring to a fix for this: "Using regedit, go to key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D. The "Trusted Installer" has ownership of this key. Change ownership to Administrators, then grant "Full Access" to the Administrators. Now run the DX Control Panel (as admin, of course). Now the changes should be saved."

LOL... thanks for citing me.

Is this new in 8.1; I mean, was the key present in Windows 8.0?

I don't know, never had win8.0, I've been hanging onto win7 as long as I can, but everything just got updated straight to 8.1 at the office so I'm a bit stuffed.

The fix that I posted a few days ago about the registry key (http://www.gamedev.net/topic/644399-d3d9-64-bit-debug-runtime/) was for Windows 7, where it works. I have not yet found a solution for Windows 8.

Just a vague guess... maybe a 32 / 64 bit issue? Is the key located under HKEY_LOCAL_MACHINE\Software\Wow6432Node?

Yes, there is a Direct3D key in there - woo!. However, I can't follow the original fix, as permissions work differently in win8.1 than in win7 so not really sure what to do.

:(

Does this help:

Sorry, can't check myself. My daughter has the only Win 8 computer in house, but my wife painted that room today and pulled out all the jacks...

Setting the keys in the registry under Wow6432Node to 1 do change some settings in the 32-bit Direct3D 9 control panel. It does however not enable debugging or remove the gray-out, that must be controlled by something else.

Debug runtime of the "old legacy" DirectX SDK (2010 and prior) don't work on Windows 8/8.1 and even on windows 7 SP1 with Platform update as far as I know. This is why PIX don't works on those platforms.

If you want debug dx9 code, you need a machine With Windows 7 (without the platform update) or a previous OS.

The fix I posted above enables the use of debug runtimes on Windows 7 even after SP1.

The platform update was the breaking change, though. That's the one in kb2670838 where the D3D11.1 components came in and wrecked everything.

The only way to get the debug version of Direct3D 9 for Windows 8 is to install a 'checked' version of the OS.

Thanks for all the help, I did manage to take ownership of the registry keys (finally), but it doesn't make any difference. This does seem a bit of a heavy handed move by MS, not sure what a "checked" version of win8.1 is or where to get it. A bit of text output doesn't seem a lot to ask for those of us forced to maintain old code (surely hundreds?).

I think that the only thing we need from the "checked" version is the d3d9.dll & d3d9d.dll. (I'm just speculating, might be more that is needed)

I made a test and copied the d3d9d.dll from my Win7 machine to C:\Windows\SysWOW64\ on my Win8 machine. Obviously is does not work, but one can note that the Direct3D 9 control panel is no longer grayed out. It would be nice to know if there is a d3d9d.dll out there somewhere for Windows 8

"checked" version aka Debug Symbol installed? Here are the installers: http://msdn.microsoft.com/en-us/windows/hardware/gg463028.aspx

The ISO with Symbols is also available on MSDN and Dreamspark Premium accounts..

Downloading the symbols won't get you a checked build. Unfortunately you need a DreamSpark / MSDN subscription.

I'd suggest dual booting an older retail version of Windows instead.
