Re-installing the drivers is not always a trivial procedure. This is especially true if upgrading the USB driver to the latest revision. To do this properly, the old ANT USB driver must first be completely removed from the system. Unfortunately, this is not as easy as uninstalling the driver via Device Manager. To completely remove the ANT driver, please follow the technical note D00001222 - TN01 Uninstalling USB Drivers. Once the old drivers are completely removed, the new drivers may be installed using the standard procedure.
