Analysing logs

An error that can be found in an MSI log of an Acronis product is usually the result of a standard or custom action of the installation process. When it is necessary to find such an error in the MSI log, you should open it with a text editor (e.g. notepad) and search for the following phrase:

  • Return value 3 (for English logs)
  • Rückgabewert 3 (for German logs)
  • Возвращенное значение 3 or Код возврата 3 (for Russian logs)
  • Valeur renvoyée: 3 (for French logs)
  • Valor devuelto: 3 (for Spanish logs)
  • Valor de retorno 3 (for Portuguese logs)
  • Valore restituito 3 (for Italian logs)
  • Vrácená hodnota: 3 (for Czech logs)
  • Retourwaarde 3 (for Dutch logs)
  • 戻り値 3 (for Japanese logs)
  • 傳回值 3 (for Chinese logs)
  •  Dönen değer 3 (for Turkish logs)

Once this phrase is found, you should look at the lines, which immediately precede it. These lines have information on what module of the Acronis product fails to be installed and why.

If Return value 3 cannot be found, then you may try searching for the first instance of the following phrase:

  • Rollback:

Once again, you should then check the lines that precede it.
