Inventor Fusion is not one of the products listed when you try to install from the 2014 install media.
In its actual form, it has been discontinued and its replacement is Fusion 360 on our cloud platform.
We released an updated version for 2014 release called Inventor Fusion 2013 R1.
It is available from the following address http://labs.autodesk.com/technologies/fusion and it is free to all customers.
A note for users running Fusion 2013, please check out this known issue:
Thank you to Kevin Schneider for clarifying.
