Thank you very much for your quick response.  I really appreciate the assistance.  This has happened several times and I am really tired of reformatting my hard drive.  This will make life so much easier.  My thanks.  

Turns out I actually need the "Integrated Webcam Driver - R216115.  It seems it is corrupted.  When I try to run the driver program I get " An error occurred while setting up the driver."  Then the program finishes and asks if I would like to restart the computer to finish the installation.  Which of course never happened.  Is this available to download?.  I only find an update.  I need the whole thing again.
