Update not completing

I was prompted to update Zwift yesterday.  It seemed to go through the process however it will not complete the process.  How can I get this to complete?

 

Hi Pam,

Try uninstalling Zwift, downloading the launcher from our website again, deleting the ‘Zwift’ folder from your downloads, and then trying again.

Additionally you can try restarting your router/modem first (unplug it for 20 seconds then plug it back in) and attempting to start Zwift again.
