The cheapest solution is to download the free software from Nikon - View NX-i and Capture NX-D.
There are better solutions out there - On1, Capture One, Lightroom/Photoshop CC, DXO Photolab, etc.
But the bigger question is if you can run any new software on your computer, especially if it is the same vintage as CS2.
There are other cheap or free solutions, but I wouldn't recommend them. They can be more trouble that the savings are worth.
