Error message

The selected release does not contain a downloadable update package.

What it means

InvalidOperationException thrown by AppUpdateService.PrepareInstallAsync when the given UpdateRelease is null or its IsInstallable flag is false, i.e. the GitHub release has no downloadable asset/attached update package. This is a caller-side precondition check before delegating to the installer.

Solutions

1. Check release?.IsInstallable == true before calling PrepareInstallAsync and disable the install action otherwise
2. Ensure the update-check code only surfaces releases that contain installable assets
3. Catch the InvalidOperationException and show a 'no downloadable package for this release' message
4. Refresh the release list — the asset may have been attached after the cached release data was fetched

Example fix

// before
await updateService.PrepareInstallAsync(release);
// after
if (release?.IsInstallable == true)
    await updateService.PrepareInstallAsync(release);
else
    MessageBox.Show("This release has no downloadable update package.");

if (release == null || !release.IsInstallable)
    throw new InvalidOperationException("Release is not installable");

try { await updateService.PrepareInstallAsync(release); }
catch (InvalidOperationException) { MessageBox.Show("This release has no downloadable update package."); }

When it happens

Trigger: Calling PrepareInstallAsync with a release that only has source-code archives and no binary asset; passing a null release; a release whose asset list failed to parse so IsInstallable stayed false; calling install from a 'check for updates' flow without verifying installability.

Common situations: Self-update on releases where the CI pipeline failed to attach the zip; draft/prerelease releases without assets; UI enabling the Install button for every listed release.
