Dear all,

I've just installed a game in Windows 7. However, after installing, i couldn't start the game. An error came up like this:

"Could not find any compatible Direct3D devices. Please make sure that the correct graphics driver is installed on your system, and Direct3D acceleration is enabled".

I did come to the DirectX Diagnostic Tool to check. In System tab, i found that DirectX version is DirectX 11. In Display tab, all three DirectX features "DirectDraw, Direct3D and AGP Texture acceleration" are all not available. And i couldn't find the "Enable" button to activate. It's not like Windows XP that you can find "Enable" and "Disable" buttons. It appeared nothing here but "Not available" line.

I've already installed DirectX 11 SDK and DirectX 11 End User Runtimes. I also try to update graphics driver (however, windows 7 announced that the current driver is up to date).

I'm using Laptop Compaq Presario CQ42 262TU; Intel® Core™ i3-370M (2*2.40GHz, 4Threads);Intel® Graphics Media Accelerator HD 500.

PLEASE HELP ME WITH THIS SITUATION!!!

I spent over 5 hours on this one and finaly figured it out. 

Use REGEDIT and change the "SoftwareOnly" key from "1" to "0" in the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D\Drivers

and then reboot the system and it should work.

The problem was the DXDIAG under 64bit worked fine but it was disabled for 32bit programs.

    I have the same issue as the OP but when I go to  HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D\Drivers there is no "SoftwareOnly" key to be found.

    There are 3 folders in the \drivers\ folder: Direct3D HAL, Ramp Emulation, RGB Emulation

    They all contained: Base, Description, GUID

    Ērik,

    Man ir tāda pati problēma, kā jums, vienīgi man ar Tesssa ir vienāda problēma:

    man zem "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D\Drivers" nav "Software Only"

    attiecīgi tagad esmu izmisumā :(

    Man liekas, ka mana video karte neiet.. ?!?

    dators: ACER Aspire V3 771G

    CPU: Intel® Core™ i53230M 2.6GHz

    video: Nvidia® GeForce® GT 740M 4gb

    ram 6gb DDR3

    DirectX: 11

    Draiveri: "up to date" - visi

    Aiznesīšu uz garantiju, sacelšu haju, ka šie iesmērējuši man k-kādu "pakaļdarinājumu"

    Choose the driver folder. Choose the one Reg file there. Right click and modify binary data. There is word written  Software and under it 0 or 1
