Postup řešení

  1. 1 Restart PDF24 Creator completely. Close it, open Task Manager (Ctrl+Shift+Esc), find any remaining PDF24 Creator processes, right-click → End Task. Background processes from previous sessions are the most common cause of startup crashes.
  2. 2 Update PDF24 Creator 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 PDF24 Creator settings. Navigate to %APPDATA%\PDF24Creator and rename the settings folder to add '.old'. This forces PDF24 Creator to create fresh settings — corrupted config files cause crashes.
  4. 4 Run PDF24 Creator as Administrator. Right-click the shortcut → Properties → Compatibility → check 'Run as Administrator'. Some features of PDF24 Creator require elevated permissions.
  5. 5 Check if PDF24 Creator conflicts with your antivirus. Temporarily disable real-time protection and test. Add PDF24 Creator installation folder to antivirus exclusions.
  6. 6 Clear PDF24 Creator cache. Navigate to %LOCALAPPDATA%\PDF24Creator\Cache and delete all files. Corrupted cache data causes rendering and processing errors.
  7. 7 Repair PDF24 Creator installation. Windows Settings → Apps → PDF24 Creator → Modify → Repair. This replaces damaged program files while preserving your data.
  8. 8 If PDF24 Creator still won't work: uninstall from Settings → Apps, restart, reinstall from official website. A clean install is the nuclear option but fixes almost everything.
