Get comfortable and learn about How to Fix Error 0xc000007b "Application was unable to start correctly", because here is everything you need.

DLL files may be corrupted or missed more frequently, and therefore generally create the problem of 0xc000007b. In some cases, these corrupted DLL files are a result of malware infections or the interference of antivirus software. Applications load DLL files into RAM for supporting advanced functionalities such as graphics and music.

Another probable cause is the utilization of 32-bit DLL files on a 64-bit Windows machine or downloading the application/game from some unofficial source.

When this happens - while launching programs.

The fifth solution is the best.

Caused by: DLL(s) corruption

Signs: Inability to launch the application.

Many programs can share the same DLL file at the same time. At their creation time, their primary purpose was to reduce the quantity of code required for basic application functionality like processing of images and sounds. Despite being a part of Windows constituents they have the ability to be auto-downloaded in an instance of corruption by means of downloading the VC runtime.

1. Installation of VCRedistributables

Since different versions of Microsoft Visual C++ include separate DLLs performing different functions to applications, including it's recommended to reinstall all of them if corrupted DLLs are encountered. There are two possible ways to fix broken dynamic link libraries: to reinstall the components needing them or to download a new DLL and replace the broken one.

Press the Windows key plus R to enter the Run dialog box.

In the 'Programs and Features' box accessed by typing appwiz.cpl and clicking OK, right-click on each of the entries which say Microsoft Visual C++.
