No sound after Windows 10 update AND I get an error message when I try to install Dell System Detect

I have an Inspiron 13 7000 series 2-in-1 and i frequently lose sound after system updates. Normally I just uninstalled the Conexant SmartAudio component and driver, reboot and the new driver magically appears. Not so this time. So I went to Dell to find the right driver. They require I install their System Detect software but I get an error message (see below). Any help is greatly appreciated.

Thanks!
