Update never finishes downloading

[JordyGit]

Version

V4.14.0

Describe the bug

On startup the emulator asks me to update and gives me 3 options where I selected the option to download/install the new version now. The window with "Downloading..." and a Dismiss button appears. There is no more feedback about the download (no download speed, no progress feedback, nothing) and it keeps this way. I left this for a whole day untouched and it still didn't complete. The only thing I can do is dismissing it with that button.

To Reproduce

1. Have an older emulator version (V4.14.0)
2. On Startup it will ask to update its version, select to do that now
3. Downloading window appears but never finishes (bug)

Expected behavior

Download window should give feedback about the download, for example the progress as a percentage.
If something is/goes wrong it should give feedback instead of doing nothing.

Not sure if related, but when I select Check for update..., I get no response from UI at all. Currently running 4.14.0.

The same issue occurred for me as well when attempting to upgrade from 4.14.0. I ended up uninstalling it, downloading the installer for the latest version, and reinstalling to get to 4.14.1.

Hello @tonyanziano could you take a look at this?

[benbrown]

@JordyGit We are taking a look into this today.

[tonyanziano]

I've repro'd this on my end, and I found the following error message which seems to be the culprit:

An error occurred in the updater's "update-available" event handler: Error: There was an error while trying to download the latest update: Error: ENOENT: no such file or directory, open 'C:\Users\tonya\AppData\Local\Programs\Bot Framework Emulator\resources\app-update.yml'

I'm unclear on why this is an issue now when it never was before. I would assume that it has something to do with the Electron upgrade, but this issue is present in 4.14.0 which is still on the older version of Electron.

As a workaround for now, you can go to your Emulator installation directory, and create a file called app-update.yml at the path:

<Emulator-install-dir>/resources/app-update.yml

with the content:

updaterCacheDirName: '@bfemulatormain-updater'

I just tested an update after adding this file, and it seems to have unblocked the update and everything worked as expected.

Note to fixer: We need to have this file generated as part of our build pipeline. Either by manually copying it in or by getting electron-builder to generate it again.

Still hitting this issue, and it's impacting certification courses on MS Learn. Any updates on a fix?

[JordyGit]

@ivorb there is a workaround commented here: #2347 (comment)

@JordyGit understood, that works or reinstalling with newer version works, but not a good experience for our learners doing labs. Is the idea that future versions won't hit this, and this issue for 4.14.0 is a won't fix?
