Case 2. VC++ redistributable packages

Some libraries refer other runtime packages which are downloaded from VC++ redistributable packages. Some Windows OS doesn't include those packages by default. Please check if there is any uninstalled VC++ redistributable packages on your platform, and install the corresponding version. You can check missing version on your environment using tools such as 'All in one runtimes' etc.
