Been the next step here, the first one is installed by default (the next step has been no pit);
The second is a custom installation (emphasis speak here)

Click to Browse...select a custom directory, I chose to put: D:\mongodbdirectory, clicknext
Whether the data in the database mongodb unified directory?
If so, the Data Dirctoryoption to: D:\mongodb\data\db, and then the next step.

D:\data
D:\data\db
D:\data\logs
D:\data\logs\MongoDB.log
Then the next step.
