There will be a driver installation CD in the package of the newly bought camera. If there is no driver installation CD, you will be prompted to install the hardware when you plug it into the computer for the first time (unless you cancel the prompt to install the hardware or the camera is bad). If there is no prompt, you will download a driver wizard online and install the driver yourself.(If it still cannot be installed or does not respond, it can prove that your camera is broken or your computer interface is faulty).You should have no problem trying it my way.
