Adjust your screen resolution (usually found somewhere in the display tab of the control panel) to fit your screen. I had the same problem with my new laptop but that is how you fix it.

I had the same problem as you. I'm pretty sure you have a Windows 7-64bit

The problem is in the NF installer uses the default program files folder. In that folder I got the same result as you.

solution:
NF uninstall
NF reinstall but have to go to the Program Files (x86) instead of the Program files.

Restart your PC and go.

To me it has worked perfect.
Best of luck.
