Dolphin 4.0-7840 not detecting Xbox 360 controller for Windows

[ahayden99]

I am currently running Dolphin 4.0-7840 and am trying to emulate super smash bros melee and play on netplay with some friends; however, dolphin doesn't detect the controller. Windows detects the controller just fine and the controller can be seen in devices and printers in the control panel however it doesn't show up in dolphin's drop down menu in the controllers section (see picture). When I select either the first or second option in the drop down menu and move the control sticks nothing happens, so further confirmation that nothing is detected.

Any help would be appreciated!
