Trouble installing hardware

I have a Sansa Clip MP3 2GB player I just purchased.  It has a small disk that says to install, but when I try to install it give an error “Cannot install this hardware.  There was a problem installing ‘MTP device’”.  Need help please!

You dont need that disk. Just plug your clip into the computer. If you still get this error, Make sure you have Windows media player 11 installed as it has the MTP drivers.
