direct3D acceleration is not available in Windows 7

Anonymous

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.

"At first I had windows XP 32 bit on my computer, and after installing Tomb Raider (2013) I was able to run it... I'm using ATI Radeon HD 5450."

Interesting. I suppose that as XP only has DX9 the game couldn't force DX11.

Also unusual for a game to default for what are effectively high or ultra settings as most

games will go for settings below the capabilities of the card they detect.
- If you used the configuration files (or saves in some cases) that were in your User folder on XP
(if there were any), after upgrading to Win7 64bit they would have also been a potential source

of the problem.

Anyway - Maybe because system set-ups vary so much, it's not uncommon for games fixes that

are not necessary for some to work for others.

Another example is putting a Direct X file in a games install folder.

Maybe I missed it before you used the link tool, but I didn't see the part below -
