I tried to update to the new version, 22.214.171.124 and I got the error message 'Garmin Express could not be installed on this computer'. I uninstalled the old version, tried installing the new version off the web, same error. I tried restarting. I tried everything else on https://support.garmin.com/en-US/?faq=iG5lWLNQ4W2I6jvUu5cBh5 . I have run it as administrator. I uninstalled Garmin Webupdater. I have tried maybe 20 times.
The only thing I find interesting is that, after clicking Yes on the UAC prompt, it says 'Initializing' for ~25s, then says 'Installing vc_redist.x86.exe' for half a second. I wonder if it's invoking vc_redist.x86.exe wrong or misinterpreting a response. There are no logs anywhere, which is super frustrating.
