RuntimePack – Install all versions of Microsoft Visual C++ Redistributable Packages at one go

The runtime library (RTL for short) is literally the library file that a program needs when it's running. It is usually provided in the form of dynamic-link library (DLL for short), and generally includes various functions that are commonly used in programming. It is a practical way to implement the concept of sharing function libraries in Windows. The extensions of these library function files are mainly *.dll, *.ocx (ActiveX control library), and *.drv (old system driver).
