Arduino drivers won't install.

I have recently bought a Arduino and I connected it to my computer expecting it to show up as ether Arduino Uno or unknown device instead it shoes up under Universal Serial Bus Controllers as a Unknown Device. I have gone through the normal install process as listed on the site and It will not install the drivers. I try selecting the arduino drivers from the folder but it shows up and says make sure drivers are compatible for your system. I have tried everything! Anyone have any Ideas?

Post a link to where you got the board from so that we can see which USB to serial converter it has. We can then direct you to getting the correct drivers loaded.
