i18n.GetString("LivelyExceptionNotLivelyZip")

Error message

i18n.GetString("LivelyExceptionNotLivelyZip")

What it means

Thrown by LibraryViewModel.AddWallpaperFile in a different non-package else branch — same intent as error 11 (file is not a valid lively package) but using the localized string LivelyExceptionNotLivelyZip. Fires on a content-check failure where the extension path took a different branch.

Solutions

1. Use a known-good lively package file.
2. Pre-screen dropped files with FileTypes.IsWallpaperPackage and show a friendly localized error before invoking AddWallpaperFile.
3. If you control packaging, ensure CreateWallpaperPackage writes the marker/manifest the validator expects.

Example fix

// before
throw new InvalidOperationException(i18n.GetString("LivelyExceptionNotLivelyZip"));

// after — guard earlier and give the user a recovery path
if (!FileTypes.IsWallpaperPackage(filePath))
{
    await dialogService.ShowMessageAsync(i18n.GetString("LivelyExceptionNotLivelyZip"));
    return null;
}

if (FileTypes.IsWallpaperPackageExtension(filePath) && !FileTypes.IsWallpaperPackage(filePath))
{
    await dialogService.ShowMessageAsync(i18n.GetString("LivelyExceptionNotLivelyZip"));
    return;
}

static bool IsAddablePackage(string filePath)
    => FileTypes.IsWallpaperPackageExtension(filePath) && FileTypes.IsWallpaperPackage(filePath);

try { await libraryViewModel.AddWallpaperFile(filePath, autoSetWallpaper); }
catch (InvalidOperationException) { ShowError(i18n.GetString("LivelyExceptionNotLivelyZip")); }

When it happens

Trigger: AddWallpaperFile on a file whose extension suggested a package but the package-content check fails (IsWallpaperPackage false), landing in this else branch.

Common situations: Same as error 11: mis-named archives, repackaged/incomplete lively packages, third-party zips with the wrong extension.
