Kernel security check failure in Photoshop, how to fix it?

Fix – Kernel security check failure in Photoshop

Solution 1 – Start Photoshop in Safe Mode

Safe Mode is designed to run with only default services and drivers enabled, so you might to try starting Photoshop in Safe Mode. To enter Safe Mode, do the following:

  1. Hold the Shift key on your keyboard and click the Restart button.
  2. Choose Troubleshoot > Advanced options > Startup Settings and click the Restart button.
  3. After your computer restarts, you’ll see a list of options. Press the appropriate key to choose Safe Mode. You can use any version of Safe Mode for this process.
  4. After you enter Safe Mode, try running Photoshop.

If the error doesn’t appear in Safe Mode, it means that is caused by your drivers or some other third-party software.

If you’re still having issues on your PC or you simply want to avoid them for the future, we recommend you to download this tool to fix various PC problems, such as file loss, malware and hardware failure.

Solution 2 – Roll back your Nvidia drivers

Photoshop utilizes your graphic card for processing, and it seems that there’s an issue with the latest Nvidia drivers and Photoshop. According to users, you can fix this problem by rolling back to the previous version of Nvidia drivers. To do that, follow these steps:

  1. Press Windows Key + X to open Power User Menu. Select Device Manager.
  2. When Device Manager opens locate your display adapter and double click it to see its properties.
  3. Go to the Driver tab and click the Roll Back Driver button.
  4. After the rollback procedure is completed, restart your PC and check if the problem is resolved.

So far, only Nvidia users reported this issue, and AMD users shouldn’t be affected by this problem. If you have AMD graphic card and you’re having this problem, you might want to try this solution.

You can also try to uninstall your Nvidia drivers completely and install the older version of the drivers. You can do that from Device Manager, or you can use Display Driver Uninstaller software. Users suggest using Display Driver Uninstaller because it deletes all files associated with your Nvidia graphic card. After removing the driver, simply download the older version and install it, and Photoshop should start working without any problems.

Solution 3 – Move or delete sniffer.exe

Sniffer.exe is a small application in Photoshop folder that is designed to use your graphic card. Apparently, there’s a problem with this application that is causing Kernel security check failure error to appear, and only solution is to move or delete this application. To do that, follow these steps:

  1. Go to Photoshop installation directory. This directory is usually C:\Program Files\Adobe\Adobe Photoshop CC 2015, but it can be different depending on the version of Photoshop that you’re using.
  2. In the Photoshop directory locate sniffer.exe or sniffer_gpu.exe and move it to your Desktop or any other folder. You can also delete this application, but we suggest that you keep it in case you need it.

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.

Solution 4 – Use your dedicated Nvidia card with Photoshop

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. To do that, follow these simple steps:

  1. Start Nvidia Control Panel and go to Manage 3D settings.
  2. Select 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.

Solution 5 – Disable your graphic card

This solution applies if you have both dedicated and integrated graphic card. According to users, after disabling the dedicated graphic card the issue with Photoshop was fixed. To do that, follow these steps:

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

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.

Solution 6 – 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.

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.
