For what it’s worth, the easiest way to update on W10 and newer is winget.
winget upgrade --all
will update all packages that you have installed, and Zwift Launcher 1.1.3 is already in the repo. Do that routinely and you can have everything from VC redists to 7-Zip to Zwift updated.
Or, if you only want to update Zwift:
winget upgrade --id Zwift.Zwift
