Solution Steps

  1. 1 Restart StartAllBack completely. Close it, open Task Manager (Ctrl+Shift+Esc), find any remaining StartAllBack processes, right-click → End Task. Background processes from previous sessions are the most common cause of startup crashes.
  2. 2 Update StartAllBack to the latest version. Open the app, go to Help → Check for Updates (or download the latest installer from the official website). Updates fix known bugs and compatibility issues.
  3. 3 Reset StartAllBack settings. Navigate to %APPDATA%\StartAllBack and rename the settings folder to add '.old'. This forces StartAllBack to create fresh settings — corrupted config files cause crashes.
  4. 4 Run StartAllBack as Administrator. Right-click the shortcut → Properties → Compatibility → check 'Run as Administrator'. Some features of StartAllBack require elevated permissions.
  5. 5 Check if StartAllBack conflicts with your antivirus. Temporarily disable real-time protection and test. Add StartAllBack installation folder to antivirus exclusions.
  6. 6 Clear StartAllBack cache. Navigate to %LOCALAPPDATA%\StartAllBack\Cache and delete all files. Corrupted cache data causes rendering and processing errors.
  7. 7 Repair StartAllBack installation. Windows Settings → Apps → StartAllBack → Modify → Repair. This replaces damaged program files while preserving your data.
  8. 8 If StartAllBack still won't work: uninstall from Settings → Apps, restart, reinstall from official website. A clean install is the nuclear option but fixes almost everything.
