Windows 10: direct3d initialization failed device d3derr_invalidcall windows 11

Hello Microsoft Teams,I upgraded my laptop from Windows 10 to windows 11. I want to use this app called PmxEditor, When suddenly this error starts to showed up. I used any method just to removed this error, But It kept on showing, The Pmxeditor Doesn't showed up. Pmx editor works perfectly in Windows 10. Do i need to download something so this error doesn't showed up again?Thank you!

Direct3D Initialization Failed

Attempting to launch a game after installing from CD, I got the following error:

Initialization failed. Direct3D Initialization failed. Possible causes:

Old or corrupted graphics driver (this is a brand new laptop)

Direct3D improperly installed (dxdiag says Direct3D enabled and working)

Hardware acceleration disabled (don't know)

Starting the app with the workstation locked (don't know)

Please check the log file for more information (don't know how to do this)

Doesn't read like a game issue. I could use some help. Thanks so much.

 

Failed to initialize Direct3D

I'm currently on Windows 10 and whenever I start a game it says:

"Failed to initialize Direct3D.

Make sure you have at least DirectX 9.0c installed, have drivers for your

graphics card and have not disabled 3D acceleration

in display settings.

InitializeEngineGraphics failed."

My Direct3D is enabled but I can't seem to find the DirectX 9.0c.

Hope anyone can help me.

Thanks in advance.

 

Direct3D application in multi display full screen mode fails on Windows 10

We are developing an application using Direct3d 9. It runs in full screen mode and utilizes multiple displays if you have them connected to your computer. This application works fine on Windows 7, but fails on Windows 10.

I have created a simple test application that fails in a similar way. If I run it in full screen mode but on one display only, then it works. But if I switch to running on multiple displays, then it fails.

The code that fails is when it's trying to create the multi-head Direct3d device. The function call looks like this:

HRESULT res = g_pD3D->CreateDevice(

D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, mainWin,

D3DCREATE_HARDWARE_VERTEXPROCESSING | D3DCREATE_ADAPTERGROUP_DEVICE,

d3dpp, &g_pd3dDevice

);

The Direct3d device (g_pd3dDevice) becomes NULL and the function returns D3DERR_INVALIDCALL. This code works fine, and has done so for a long time, in Windows 7.

I have tried creating a similar test app using Direct3d 11, and though it seems to handle multiple displays in a very different way to version 9, it also fails in a similar matter.

It seems to me that support for full screen mode with multiple displays is dropped in Windows 10. Does anyone have any insight in this?

Thanks
