This driver will have to be installed. When you download it just click open and it will self install. Then restart the comptuer and plug in your mp3 player, or plug it in when prompted to do so during teh installation. Then it will show up in my computer after the driver has fully installed (it will probably complete installation after you restart the computer) and you will be able to click and drag songs onto it.
Method 2 that I thought of:
Plug in your mp3 player after saving the download to your desktop or an easily accessible folder. Go to start>settings>Control Panel>Add new Hardware. As it searches, it should be able to recognize a new device. When it asks if you want the computer to search for a driver or for you to manually pick the location of teh driver, say picka location and browse until you find the folder the driver is stored in. Allow it to install and follow the instructions.
