Error code 0xc0000142 indicates that the program fails to initialize when starting up, which is commonly found in old or poor compatibility software. 1. First check the integrity of the system file, run the sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth commands as administrator to repair the system files; 2. Try running the program in compatibility mode, right-click the program to select properties and select the compatibility mode and administrator to run in the compatibility tab, and disable full-screen optimization; 3. Clean or reinstall the runtime library dependencies, enable the .NET Framework and install the latest VC runtime library, and reinstall the problem software if necessary; 4. Delete temporary files and user configuration caches, clear relevant files in %temp% and %appdata% to eliminate configuration corruption.

This error code 0xc0000142 usually indicates that a program fails to initialize at startup, and is often found in old or poorly compatible software. The problem may be in the system files, registry configuration, or the software's own dependencies. The following are several practical troubleshooting and repair methods.

Check system file integrity

Corrupted Windows system files may cause the application to fail to load properly. You can check and repair these files through the system's own tools:

• Open a command prompt (administrator permissions)
• Enter sfc /scannow to press Enter and wait for the scan to complete
• If you find a corruption but it is not automatically repaired, you can try running DISM /Online /Cleanup-Image /RestoreHealth

This step is helpful for most system-level errors and is recommended to perform it first.

Try running the program in compatible mode

If you are running older software, such as some games or office tools from a decade ago, it may not be compatible with the current Windows version:

• Right-click on the program shortcut or executable file
• Select "Properties"
• Switch to the Compatibility tab
• Check "Run this program in compatible mode" and select an older version of Windows (such as Windows 7 or Vista) from the drop-down menu
• At the same time, check "Run as administrator" to try

Sometimes, even if the compatibility mode is not enough, you can try to disable full-screen optimization (there is a button to "Change High DPI settings" under "Compatibility" and there are related options in it).

Clean or reinstall software's runtime dependencies

Many programs rely on runners such as Visual C Redistributable or .NET Framework. If these components are corrupted or version conflicts, it can also cause an error of 0xc0000142:

• Control Panel → Programs → Enable or turn off Windows features
• Make sure .NET Framework related features are enabled
• Go to Microsoft's official website to download the latest version of VC runtime (both x86 and x64 are installed once)

If you are sure it is a problem with a specific software, you can also uninstall and reinstall it to ensure that its dependencies are deployed correctly.

Delete temporary files or user configuration cache

Some programs generate temporary configuration files in the user directory. Once these files are corrupted, the program cannot start normally:

• Close the program that reports an error (if it can still be opened)
• Press Win R, enter %temp% and enter
• Clear the contents under this folder (be careful not to delete the files you are using)
• Try running the program again to see if there is any improvement

In addition, you can also try to clean the cache in AppData:

• Press Win R, enter %appdata% to see if there is a folder for the corresponding program. You can temporarily change the name or delete it.

Basically these commonly used methods. It is not particularly complicated, but every step is quite critical, especially the system files and runtime libraries, which are easily overlooked.
