MongoDB YAML Configuration File Problem

I am trying to install MongoDB 3.0 as a windows serverice on Windows Server 2008 however I get that error.

Error parsing INI config file: unknown option storage.engine try 'e:\mongodb3\bin\mongod.exe --help' for more information

But my configuration file is YAML formatted.

My configuration file:

storage:
    dbPath: "E:/mongodb3/data/"
    engine: "wiredTiger"     
systemLog:
    destination: file
    path: "E:/mongodb3/log/mongodb.log"
    logAppend: true
net:
    port: 29000

Also I have tried to start mongodb with mongod.exe --config e:\mongodb3\mongod.cfg command and it was working correctly.

I didn't find what is my mistake.
