SysManager 1.52.86 ڈاؤن لوڈ

[1.52.86] - 2026-07-10
Fixed
- On a PC without winget (App Installer), the App Updates and Uninstaller tabs popped a raw OS-error dialog on their first action instead of a friendly message. All winget calls launch winget.exe via Process.Start; when App Installer isn't present or its execution alias is off (common on older/LTSC/Server machines), that throws Win32Exception ("The system cannot find the file specified"). AppUpdatesViewModel.ScanAsync, AppUpdatesViewModel.UpgradeSelectedAsync, and UninstallerViewModel.ScanAsync caught only OperationCanceledException/InvalidOperationException, so the Win32Exception escaped the generated AsyncRelayCommand to the global dispatcher handler and surfaced as a bare OS-error dialog on the tab's very first action. (The sibling UninstallerViewModel.UninstallSelectedAsync already handled this — a missed migration of that fix.) All three now catch Win32Exception and show a shared plain-language message ("winget (App Installer) isn't available on this PC — install "App Installer" from the Microsoft Store to use this tab."). The upgrade batch stops on the first Win32Exception (winget won't reappear mid-run) and keeps the friendly message instead of a misleading "Updated 0 of N" summary.
