Lost original factory CD Software for my Nikon D3000

SOURCE: Nikon Coolpix L18 Driver

You don't need the disk to transfer your pictures from your camera to your computer. Just take your sd card out of your camera and plug it into your computer. A folder with your pictures will appear on your computer. Copy them to a different folder on your computer, so you can take your sd card out and still have them on there.
If that doesn't work, plug the cable in that came with your camera, and hopefully that will work. I hope this helps. Please rate my solution.

Try this, it may work without the software.  Turn off the camera. Plug the usb cable between the camera and the computer. Turn on the camera. If a box pops up on the computer asking what you want to do, scroll down and see if there is an option to view pictures. If a window opens up with all your pictures on it, great. Now open up a folder where you want to put your pictures. Bring up the other window with the pictures in it and hit the control key and the d key at the same time on your keyboard. Then drag your pictures to the window where you want them and let go of the mouse key.  They should all move over. Then you can use Windows image viewer to see them. Let me know if that works.

Most often the manufacturer will have a support and downloads area on their website.  You may find what you need here: http://www.nikonusa.com/Service-And-Support/Download-Center.page

SOURCE: how to remove the battery from nikon d3000

the little trap door on the bottom houses both the memory card and the battery. you have to push the battery slightly to release it. i fond the easiest way at that point is to tip the camera and the battery usually slides right out.
