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