« on: August 08, 2016, 05:43:54 AM »
    Symptoms
    When you back up files by using Windows Backup on a computer that is running Windows 7, the backup fails and you receive the following error message:An internal error has occurred: The parameter is incorrect: (0x80070057)

    Resolution
    To resolve this problem, use one of the following methods:

    Method 1:

    Change the decimal symbol settingThis problem can occur if the decimal symbol is not set to  '.' (dot).
    This is common in languages and locales other than English (United States), such as German (Germany).

    To change the decimal symbol setting, follow these steps:[list=decimal]
    • Open  Control Panel, click Clock, Language, and Region,  and then click Region and Language.
    • Click the Formats tab, and then click Additional settings.
    • In the Decimal symbol field, type . (dot), and then click OK two times.
    • Restart the computer.
    Note Some third-party software may cause changes to the runtime locale of the computer  and override the setting in Control Panel.


    Method 2:

    Add a registry key valueWarning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
