Why does Direct3D crash dxdiag in 32-bit but work fine in 64-bit mode?


  • DxDiag crashes when I open it unless I bypass Direct3D. It works fine in 64-bit mode. I have a NVIDIA GeForce GT 525M, and I've tried updating (also uninstalling, reinstalling) my drivers. I've also tried doing the same with DirectX. How can I enable Direct3D for 32-bit? I've tried enabling hardware acceleration through `screen resolution -> advanced settings -> troubleshoot`, but I'm not able to do so as the "Change Settings" button is disabled.

    A similar issue is here:

    The proposed answer doesn't seem to work for me. Like other users in that thread, `HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D\Drivers` does not have a `SoftwareOnly` key to change. I even tried manually adding it as a string and dword, to no avail.

    To clarify, here's what I see when I open DxDiag:

    DxDiag has detected that there mgiht have been a problem accessing Direct3D the last time this program was used. Would you like to bypass Direct3D this time?

    No -> Crash
    Yes -> No crash, but in Display tab:

    DirectDraw Acceleration: Disabled
    Direct3D Acceleration: Not Available
    AGP Texture Acceleration: Not Available

    If I click "Run 64-bit DxDiag", all three are "Enabled".

  • What bit version of operating do you have?

    Why do you need to achieve DirectX to comply with 32 and 64 versions?

  • Hi,

    Since the DirectX Diagnostic Tool have an extra Run 64-bit DxDiag button, your computer should be the 64bit version.

    According to the 32bit issue, I suggest you check the steps in the following KB

    DirectDraw or Direct3D option is unavailable

    For additional information about DxDiag tool refer to the article below.

    DirectX: frequently asked questions  

    Run DirectX Diagnostic Tool  

    Hope this helps.

  • Milos, Yes, I am running Windows 7 Professional 64-bit. However, I'm trying to play a 32-bit game that uses DirectX. Up until a couple of weeks ago, it worked great (as did dxdiag).

    Thanks for the ideas, Vincent. I've actually come across all of these in my research (posting on forums is a last resort for me). Nevertheless, I've tried them again. I actually got a little excited, because my graphics card had another update come out in the past couple days, but still no luck.

    For completeness, I've outlined the result of each of these steps (

    Method 1: Configure Hardware Acceleration to use the Full setting

    I can't click "Change Settings", it is grayed out. Also, why is it showing my onboard graphics in the titlebar rather than my NVIDIA 1GB graphics card (which has a 6.6 Windows Experience index)? It almost seems like DirectX is ignoring my dedicated graphics card.


    Method 2: Enable DirectDraw or Direct3D

    There is no option to "Enable" on the screen:


    Method 3: Download and install the latest version of DirectX End-User Runtimes Web Installer

    No luck here. Just tells me: "DirectX setup has determined that a newer or equivalent version of DirectX has been installed already. No installation is necessary."

    Method 4: Update your video driver

    As I mentioned, NVIDIA did release an update in the past few days, so I got excited, but my problem persists.

    Method 5: Restart the computer by using a clean startup procedure

    No luck here.

    Method 6: Disable NetMeeting's Remote Desktop Sharing and then close NetMeeting

    I don't use NetMeeting. 

    Method 7 & 8 are irrelevant as they are for XP only.

    Any other ideas? Or am I just going to have to reinstall Windows? :( Hoping to avoid that...

  • Hi,

    According the similar thread you provided:
    direct3D acceleration is not available in Windows 7. I found some other replies showed they have change the different registry keys, you can try to change these keys and reboot the computer to check the result.

    Note: Please refer to this knowledge base (KB) article to back up the registry key.

  • Vincent, thanks, but unfortunately as I mentioned in the OP, I tried the proposed answers in that thread (each of them).

    None of the mentioned keys was in my registry, and nothing seemed to happen when I added them.

  • No ideas? :(

  • This is really disappointing. Why is DirectX so problematic?
