I'm not clear what you mean by "an update is available to install, however cannot install on a non-existant driver" but have you tried the usual. Possibly the driver still exists on the harddisk. Through the Device manager try to uninstall the driver, if it does show one is installed, and then reboot and see if the OS can reinstall something workeable. Otherwise try, by the same method, to update the driver by searching in Windows (including sub folders). You might also see, by right clicking the device in the device manager, if there is a rollback option.
