You may encounter the following error when running some software or games written using Visual Studio 20XX: Microsoft Visual C++ Runtime library Runtime Error! This proves that your system is missing the corresponding Microsoft Visual C++ Redistributable Packages as the must-have additional components (common DLL runtimes that are equivalent to the dictionary files of programs) for these programs to run properly. This is especially true for newly installed systems. This case, Visual C++ Runtime Installer can help you solve problems with one click.
