1. Problem description: An error is reported when installing mysql and the program cannot be started because VCRUNTIME140_1.dll is missing from the computer. Try to reinstall the program to solve the problem
2. Solution: This is the missing dynamic link library (.ddl file), you need to install VC_redist.x64.exe
VC_redist.x64.exe is an optimized patch execution program for different CPUs. It is a library file required by C++-based software. Some programs can only run under the environment of installing the corresponding vcredist file. When we install mysql, we need to read VCRUNTIME140_1.dll in the C:/windows/System32/ directory, and the dll file can be used normally after installing vcredist

the required dll files have already appeared in the system
and msyql is installed again.
