Well Andy,

Don't get confused with Hotfix KB2731284 message it has nothing much to do with MongoDB.  Even if you do not install this Hotfix, still MongoDB will work fine. Your actual problem is exception in initAndListen: 29 Data directory D:\data\db\ not found., terminating.
Above mentioned error message means that you have successfully installed MongoDB server successfully on your Window 7 machine. but your Windows 7 is not updated with Hotfix KB2731284

You can download and install the Hotfix KB2731284. following is the link for the same.
