Pierre Smith,

From the MongoDB website: "MongoDB 3.0 deprecates direct access to the system.indexes collection." Newer versions o Mongo do not allow access to that collection -- which is a GOOD thing, because it's used by Mongo internally. If you access and change that collection you could break Mongo on your system

If you want text instructions for installing Mongo, you can also follow along with our
