Driver Software

I am new to arduino and have a little idea of how to start. I have recently purchased the board and tried to connect to my laptop, which relies on Windows 7 OS. It only continues to give me an error message which says "Device Driver Software was not successfully installed". Does anyone have any idea how to find and install the Device Driver Software? I have followed the instructions available, but I was unable to understand quite clearly. So, if anyone has a good, quick link which I can down the software, could you please let me know. Thank you very much for the assistance.
