0xc000007bHigh0xc000007b application error
What this error means
The 0xc000007b application error usually means Windows could not start an app because one of its required files, libraries, or components did not load correctly. It often appears when you open a game, desktop app, or installer, and the program closes right away or shows a message saying it could not start properly.
This problem is commonly linked to missing or damaged Windows files, incompatible 32-bit and 64-bit components, or an outdated driver or Windows update.
Common causes
- 1A required Windows file or app component is missing or corrupted
- 2A 32-bit and 64-bit file mix-up is preventing the program from loading
- 3Outdated Windows files or drivers are interfering with the app
How to fix it
- Restart your PC. A simple restart can clear temporary loading problems and is the safest first step.
- Install pending Windows updates. Open Windows Update and install all available updates, then restart again. Missing system updates can prevent apps from starting correctly.
- Repair Windows system files. Open an elevated Command Prompt and run the built-in repair checks for system files. If Windows finds damaged files, let it finish and restart when prompted.
- Update or reinstall the app that is failing. If only one program shows
0xc000007b, uninstall it, restart, then install the latest version from the official source. This helps replace missing or damaged app files. - Install or repair the required Microsoft runtime components. Many apps need Microsoft Visual C++ libraries or similar support files. Reinstall the official runtime packages from Microsoft, especially if the problem began after a new app install or update.
- Update your drivers. If the error appears in a game or graphics-heavy app, install the latest graphics and device drivers from your PC maker or hardware vendor, then test the app again.
- Try a clean boot if the problem continues. Starting Windows with only essential services can help you find whether another program is interfering. If the app works in a clean boot, re-enable startup items one by one to identify the conflict.
