When installing the mysql service, it prompts "MSVCP140.dll VCRUNTIME140.dll cannot be found"

After reinstalling the window system, when installing the mysql service, it prompts "Cannot find MSVCP140.dll VCRUNTIME140.dll". The reason is that the VC++2015 runtime library (Microsoft Visual C++ 2015 Redistributable) is not installed. The download address is https: // www.microsoft.com/en-us/download/details.aspx?id=53587 . Click download and there are two exe files, one 64-bit and one 32-bit. After downloading and installing, the problem was solved successfully.
