I followed you link to the SanDisk Support site. If I select c200 as the Product Name to search and click on the Find Driver button, it takes me to a page where the only download option is the Sansa Firmware Updater.
This is not a driver. And you don’t need it if you’ve already updated the firmware. Even if you haven’t, it’s simple enough to do manually following the directions contained in the firmware post. You will however, need to know whether you have a v1 or v2 model as there is different firmware versions for the different hardware configurations.
As I said before, there is no driver you need to download to make this player operational, other than the one included in WMP 10 or above and you don’t even need that if you use MSC mode.
