Are you facing the 0xc000012f Windows 11 status error? I’ve experienced it before, and it’s annoying. It prevents you from accessing apps or games.
It’s usually caused by a corrupted system or app file, the absence of Microsoft Visual C++, or faulty Windows updates.
Below, I’ll give you the best solutions to fix error status 0xc000012f. Make sure to keep on reading!
Before you try any advanced fixes, I recommend starting with the following:
- Restart your PC.
- Uninstall the affected software or game, and then reinstall it from the official store.
- Relaunch the affected app
- Install pending Windows updates – Go to Settings>Windows Update>Check for Updates>Install all. Restart your system to apply them.
1. Run the SFC scan
The SFC scan repairs corrupted or missing system files, which might be the cause of the 0xc000012f Windows 11 error. If it’s unable to do so, it suggests further steps.
To run it, open Command Prompt as an administrator, copy-paste the following command, and press Enter on your computer keyboard:
sfc /scannow
Wait for the checker to run up to 100%, and then restart your computer. If that doesn’t resolve the issue, try the next solution.
2. Reinstall Microsoft Visual C++ Redistributable
The Microsoft Visual C++ Redistributable might have issues such as incomplete installation and missing or corrupted files. The best way to fix this is by reinstalling it:
- First, open the Control Panel, look for Microsoft Visual C++ under Programs and Features, and uninstall it.
- Next, go to the official Microsoft Visual C++ download page, select your PC architecture, and download it.
- Click the file in your download folder to install it. Follow the on-screen directions to complete the process.
- Once the installation is over, restart your PC and see if the issue is fixed.
Another alternative is to get the Visual C++ Runtime Installer from a secure source. You’ll be able to install the latest batch of Visual C++ files.
3. Re-register All DLL Files
DLL files have several roles in apps and the Windows OS. If they get corrupted, you might encounter issues such as the 0xc000012f error code on Windows 11.
- Go to the search bar and type Command Prompt.
- Select Run as administrator, and when you get the UAC prompt, select Yes.
- Copy and paste the following command and press Enter:
for %1 in (*.dll) do regsvr32 /s %1
If that doesn’t work, try the next solution.

The status error 0xc000012f can be caused by startup or third-party programs. Performing a clean boot is not a definite solution, but it can help you pinpoint which app is behind the error.
