Certain DLL components did not install properly.


  1. Uninstall Acronis True Image and all its components through Add or Remove Programs (Start -> Control Panel);

    • Windows 64 bit: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Acronis
    • (!) The subkey is Acronis. Do not attempt to remove the whole registry key.
