I often hear friends complain about the lack of d3dx9_xx.dll or msvcp71.dll, msvcr71.dll or .net Framework initialization errors when running software or games on his computer. In fact, most of the time, it is just because your computer does not have the runtime required for these software.

In the Windows environment, many software, especially games, rely on some runtime libraries to be used normally, but these libraries are not integrated in Windows and need to be downloaded and installed by ourselves (the required runtime is usually mentioned in the software or game description). Our most common ones are DirectX, VC++ runtime, .net Framework framework and so on.

1. DirectX (essential for playing games):

DirectX is a common application programming interface for developers, including 3D, sound, network and other multimedia. It makes game developers do not have to write different drivers for each brand of hardware, and also reduces the complexity of hardware installation and setup.

2. C++ runtime / Microsoft Visual C++ Redistributable Package:

People generally casually call it the "VC++ runtime". Installing it can make users' computers run normally using applications developed by Visual C++, especially big guys such as games. If they are not installed, they will often make mistakes, such as the lack of files at the beginning of msvc, such as msvcp71.dll and msvcr71.dll Shenma. It is a runtime, not the usual VC++ development environment, please do not confuse.

3. Net Framework (.net framework):

In fact, .net Framework is also mainly convenient for developers, it contains many features and a variety of technologies, it is estimated that it can be introduced to write a book. Anyway, it's the same as above, for example, VC programs need VC runtime, VB programs need VB runtime, and java programs need Java Runtime. Programs developed with .net need to be run under the .NET Framework.
