3. 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. 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. 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. 6 Clear Acronis True Image cache. Navigate to %LOCALAPPDATA%\AcronisTrueImage\Cache and delete all files. Corrupted cache data causes rendering and processing errors.
