Image Acquisition Tool box and Fn winvideo

Why do I receive the following error when using a camera in MATLAB R2014a ?

Error using videoinput (line 217)

Invalid ADAPTORNAME specified. Type 'imaqhwinfo' for a list of available ADAPTORNAMEs. Image acquisition adaptors may be

available as downloadable support packages. Open Support Package Installer to install additional vendors.
