MMC Could Not Create The Snap-in

Microsoft Management Console (MMC) is an inbuilt feature in Windows operating system that lets you to manage snap-in on the go (you can run mmc.exe command to access it) and provides a graphical user interface (GUI). The snap-ins are nothing but a basic component of a console. In the language of set theory, we can say that if a console is a set, then snap-in is its sub-set.
