Go to the yellow triangle, right-click, Uninstall.
With the unit off, push the power switch down into Hold position to show the orange dot. Open Windows Explorer (Computer or My Computer), plug the USB into the computer, hold down the << side of the wheel and connect the USB to the Fuze. You may get a Found/Intalling New Hardware or the Fuze may just pop up in Windows Explorer.
There’s no disc to install.
The Fuze drivers are Windows basic USB drivers and the USB drivers in Windows Media Player 10 and up. They are already in Windows.
(If you are still using WMP 9, and the Fuze is in MTP mode, then you’d need a newer Windows Media Player from support.microsoft.com–which might explain the yellow-triangle MTP device.)
But the forced connection above (HOLD/<<) goes to the generic USB driver in Windows.
