Windows 10 2004 - MSIX Not Updating -Please check whether the Msixvc support services are installed.

Hi everyone,

If anyone is interested, I have a workaround that I'm currently testing.

So, the idea is to do basically parse your .appinstaller file, download the .msixbundle locally, and launch it. Sure it sucks, but it's the best workaround I could come up with, knowing this crappy bug.
(the idea is - if you download and launch the .msixbundle, it works).
If anyone's interested, I can share the code (it's C#)

You would need to update your code:

protected override async void OnLaunched(LaunchActivatedEventArgs e) {
  if (setup_kit_util.has_update_downloaded_locally() && await setup_kit_util.launch_update_kit()) {
    Application.Current.Exit();
    return;
  }
  ...
}

and somewhere in your code's initialize routine, add this:

await Task.Run(async () => await setup_kit_util.download_update_task());

Best,
John
