Recently, Windows users have become more and more notified about the appearance of the D3DERR_NOTAVAILABLE 0x8876086A error when they try to launch a game, emulator, or any other resource-intensive application. This error is not limited to any version of Windows, i.e. almost all users can face it.
Causes of Error D3DERR_NOTAVAILABLE 0x8876086A
- Outdated version of DirectX. The most common cause is deprecated DirectX API libraries. Every game and application that leverages your GPU’s resources requires specific DirectX libraries. If the application does not find the required libraries in the system, an error occurs.
- Outdated video card driver. Another reason is an outdated driver for the video card installed in the system. The solution in this case is an elementary video driver update.
- The application is incompatible with the OS. The D3DERR_NOTAVAILABLE 0x8876086A error can occur if the application launched by the user is not compatible with the version of Windows. Compatibility mode can help, but it is not guaranteed.
- Conflict between applications. There is a small chance that the application being launched has come into conflict with another application running on the system. Perhaps some software already uses libraries and modules that are required for the applications you need to work.
- Damage to system files. In rare cases, the D3DERR_NOTAVAILABLE 0x8876086A error can occur due to corrupted Windows system files. The solution is to restore / reinstall the system.
Methods for solving D3DERR_NOTAVAILABLE 0x8876086A
In this article, you will find six methods for fixing this error that have been tested by many Windows users around the world. If one method doesn’t work, be sure to try another. So let’s start in order …
Method # 1 DirectX Upgrade
As we said above, the most common reason for this error is an outdated version of DirectX. If this is really the case, then you just need to update the libraries of this API – and the trick is in the bag. To update DirectX, you need to do the following:
- go to this link and click on the “Download” button;
- uncheck all Microsoft recommendations and click the “Refuse and Continue DirectX End-User Runtime Web Installer” button;
- wait until the file “dxwebsetup.exe” is loaded and run it;
- follow the instructions on the screen and install the latest version of DirectX;
- restart your computer.
Try running the application you want again and check if the D3DERR_NOTAVAILABLE 0x8876086A error is resolved.
Method # 2 Running the application in compatibility mode
Some older applications and games run rather poorly on newer versions of Windows. Trying to run something really old? Try using compatibility mode. To do this, you need to do the following:
- right-click on the application executable file and select “Properties”;
- go to the “Compatibility” tab;
- put a check mark next to the “Run the program in compatibility mode with:” item and select the appropriate version of Windows;
- click “Apply” and “OK”.
The note: the choice of the Windows version will depend solely on the application itself, i.e. the older the application, the lower, as a rule, the version of Windows you need to choose. However, in some cases, you can experiment with compatibility and try all versions of Windows.
Check if the D3DERR_NOTAVAILABLE 0x8876086A error occurs when launching the application you want.
Method # 3 Updating the video driver
An outdated video driver can cause a number of problems when working with programs and games that require the power of the graphics accelerator. The D3DERR_NOTAVAILABLE 0x8876086A error could also occur due to an outdated video driver.
- Press Windows + R;
- copy the value “devmgmt.msc” into the line and press Enter;
- open the “Video adapters” section;
- right click on your video card and select “Update Driver”;
- click on the item “Automatic search for updated drivers”;
- wait for the installation of the fresh driver to finish and restart your computer.
Alternatively, you can install the new video driver manually by going to the website AMD, nVidia or Intel… After downloading this or that installer, follow the instructions on the screen and you will succeed.
Typically, the first three methods in this article resolve the D3DERR_NOTAVAILABLE 0x8876086A error. But if the error still doesn’t give you life, then try the methods below.
Method # 4 Net Loading
Some software running on a Windows system could theoretically cause the error in question to appear. To understand what this software is, you need to perform a clean boot. This can be done as follows:
- press Windows + R and run the command “msconfig”;
- switch to the “Services” tab and check the box next to “Don’t show Microsoft services”;
- click “Apply” and switch to the “Startup” tab;
- click on the line “Open Task Manager”;
- disable all programs from the list using the corresponding button in the lower right corner of the window;
- restart your computer.
As soon as you log in again, try to launch the application that caused the D3DERR_NOTAVAILABLE 0x8876086A error to appear. If the error did not occur, then some service or program that you previously disabled was the culprit.
Unfortunately, the only way to determine what caused the error is to enable all disabled programs and services one by one. It will take quite a long time, but in this way you are most likely the program / service that caused the problem.
Method # 5 System Restore
If you still could not establish the cause of the D3DERR_NOTAVAILABLE 0x8876086A error, then you just have to try to restore the Windows system. To do this, you need to do the following:
- press Windows + R;
- write the value “rstrui” and press Enter;
- click “Next” and check the box next to “Show more restore points”;
- select a restore point created before installing the program / game, the launch of which causes the error, and click “Next”;
- click the Finish button to start the recovery process.
Once your system is restored, reinstall the application and try to launch it. There is a chance that this time there will be no error, but if you still encounter it, see below.
Method # 6 Returning the PC to its original state
This is the last and most effective method in dealing with the D3DERR_NOTAVAILABLE 0x8876086A error. Now we will try to return Windows to its original state, without losing important files for you. Do the following:
- right-click on Start;
- click on the “Parameters” item;
- go to the “Update and Security” section;
- go to the “Recovery” tab;
- click on the “Start” button in the “Reset the computer to its original state” section;
- then select “Save my files”.
- follow the instructions on the screen.
After returning the computer to its original state, the D3DERR_NOTAVAILABLE 0x8876086A error should have disappeared and now you can run the application you need without any problems.
