The most common cause of this error is outdated or corrupt applications. So, when you try to launch them, they start creating a nuisance and the error appears as a result.

I’ll list here all the general solutions that may help you to fix the error. Just use them one by one until you find the one working for you.

1. Update or Re-install the Application

The first solution that you should try when encountering this error is updating the app that is causing it. You can update the application by going to the Control Panel or visiting the website of the app and downloading the latest version. Also, I’d recommend that you always keep the Update apps automatically feature of Windows active. If you haven’t, follow these instructions to turn it on:

  • Go to the Start screen, and then go to Microsoft Store.
  • In Microsoft Store, choose the account menu (the three dots) at the upper right and then select Settings.
  • Now under the App updates section, set the Update apps automatically feature to On.

However, if you are already running the latest version of the application, then you need to re-install it once. Just uninstall the app from the Control Panel, Restart your PC, and then install it again. Now check if the problem still persists or it is gone.

2. Repair System Files using sfc /scannow Command

You can use the sfc /scannow command as an administrator to repair the corrupted system files. This may help you to get rid of the annoying error 0xC0000142. Follow the instructions mentioned below to know what you need to do.

  • Open Command Prompt as an administrator via accessing the Power User menu by pressing Windows + X key together.

  • Now, wait patiently until the process completes as it may take some time to finish. After completing the process, the corrupted system files will be detected and repaired.

Once everything is over, check if the problem is solved or if it is still there.

3. Verify Registry Settings

Sometimes error 0xC0000142 is caused by incorrect Registry settings as some applications may unknowingly modify them, and the modification results in incorrectly configured settings. So, I’ll guide you on verifying and repairing the Registry settings. This will help you to get rid of the problem. Follow the instructions mentioned below.

  • Press the Windows + R key to trigger the Run dialog box. Now type regedit in it and hit Enter. This will launch the Registry  Editor.
  • In the Registry Editor, you need to navigate to the following key- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\
  • Now take your cursor to the right side pane and double click on the LoadAppInit_DLLs value.
  • Next, change the value data to 0 and then click on OK to save the changes.
  • Finally, Restart your computer.

Now check if this resolves the issue. It is one of the most accurate solutions against this error. However, if the problem is still there, continue reading.

  • Press the Windows + R key to trigger the Run dialog box. Type devmgmt.msc in it and hit Enter. This will launch the Device Manager.

Alternatively, you can download the latest version of the driver from the developer’s website, and then installing it. Once everything is done, check if you are able to launch the application without encountering the error.

5. Run the Application in Compatibility Mode

If all the above-mentioned solutions have failed to work for you, you should try running the application in  Compatibility Mode. This is another very accurate solution against error 0xC0000142. Follow the instructions mentioned below in order to know what you need to do.
