The Kindle Fire driver is not needed if you only intend to use it as a storage device to get files in and out of it. The driver is however needed for ADB to recognize the “kindle” device is the device panel. ADB is needed to root, or unbrick kindle fire.
This driver was made by modifying the default google android driver by adding the kindle fire device ID to it. Or you can simply get it off the driver folder in the kindle fire utility.
Open your device manager, find the mis-installed “Kindle Driver”, right click it and select install driver, skip auto search, and local search, and specify the driver manually from the driver folder in the package you downloaded.
That should do it, this driver is also valid if your Kindle fire is in recovery mode (black screen) .
