Where is the VC runtime library installed?

VC runtime refers to the Microsoft Visual C runtime, which is a set of dynamic link library files (DLL) required to run programs developed using Microsoft Visual C on the Windows operating system. When installing certain software or games, you often encounter a situation where the VC runtime library is missing. In this case, you need to install the VC runtime library manually.

Under this path, we can view the version information of the VC runtime installed on the current computer. For example, if the version we see in this path is 14.0.23026, it means that the VC runtime version 14.0 has been installed.

According to the needs of different programs or games, you may need to install different versions of the VC runtime library. Generally speaking, the latest VC runtime version will also include previous versions of the runtime, so installing the latest version of the VC runtime can meet most needs.
