FIX: Kernel security check failure in Photoshop


Apparently, there’s a problem with this application that is causing Kernel security check failure error to appear, and the only solution is to move or delete this application.

After moving the sniffer.exe file, Photoshop should start working without any problems.

Keep in mind that moving this file will disable GPU processing in Photoshop, so if you use this feature heavily you might want to try something else.


5. Use your dedicated Nvidia card with Photoshop

  1. Start Nvidia Control Panel and go to Manage 3D settings.
  2. Select the Program Settings tab and choose Photoshop from the list of applications.
  3. Set High-performance Nvidia processor as the preferred graphics processor for this program.
  4. Click Apply to save changes, and check if the issue is resolved.

If you have both integrated and dedicated graphics card, you need to use your dedicated Nvidia card with Photoshop in order to avoid this error.

Some users are also recommending enabling Triple Buffering feature for Photoshop in Nvidia Control Panel, so be sure to try that as well. After doing that, try to start Photoshop again.


6. Disable your graphic card

  1. Open the Device Manager.
  2. When Device Manager opens, locate your dedicated graphics card, right-click it and choose Disable from the menu.

This solution applies if you have both a dedicated and integrated graphic card. According to users, after disabling the dedicated graphic card the issue with Photoshop was fixed.

After disabling the dedicated graphic card there shouldn’t be any more issues with Photoshop. Keep in mind that you’ll have to repeat these steps every time you want to start Photoshop.

Another way to disable your graphics card is to use the graphics card driver software. Sometimes these applications allow you to pick which graphics card you want to use as your graphics processor.

Alternatively, you can enter BIOS and disable your dedicated graphics from there.


7. Update your graphic card driver

Although many users reported that installing the older version of Nvidia drivers fixed the problem for them, few are claiming that installing the latest drivers fixes the problem on their PC.

To update your drivers simply visit Nvidia’s website and download the latest drivers for your graphic card. After installing the latest drivers, check if the problem was resolved.

Updating drivers manually is very annoying, so we recommend you to download this driver updater tool (100% safe and tested by us) to do it automatically.


8. Upgrade your graphics card

If Kernel security check failure error keeps appearing whenever you try to run Photoshop, the issue might be your graphics card. Several users claim that their graphics card wasn’t detected by Photoshop at all.

If you still have this problem, even after trying all of our solutions, it’s possible that your graphics card just isn’t compatible with Photoshop, so you might have to replace it.

This usually happens with older or low-end graphics cards, but if you’re using mid-range or high-end graphics, the issue is probably something else.


9. Switch to 32-bit version

According to users, Kernel security check failure error affects only 64-bit versions of Photoshop, while 32-bit versions remain unaffected.

If you’re having this problem, perhaps you should temporarily switch to 32-bit version until the issue is resolved.

Bear in mind that you might experience reduced performance with the 32-bit version, but if you can deal with slightly reduced performance, be sure to try this workaround.

Before you install the 32-bit version, perhaps it would be best to remove the 64-bit version from your PC. There are several ways to do that, but the best is to use uninstaller software such as Revo Uninstaller.

By using an uninstaller software, you’ll completely remove the desired application, including its files and registry entries. After the 64-bit version is removed, install the 32-bit version and use it instead.

Get Revo Uninstaller


Kernel security check failure error screen can be a big problem, but you can fix this problem in Photoshop by downgrading your drivers or by moving the sniffer.exe file to a different location.

We hope these solutions were helpful for you to fix this issue. For more suggestions, please access the comments section below.
