Update mode

The Update mode tab contains options related to the program component update. The program enables you to predefine its behavior when a new program component upgrade is available.

Program component updates include new features or makes changes to those that already exist from previous versions. It can be performed automatically without user intervention, or you can choose to be notified. After a program component update has been installed, a computer restart may be required. In the Program component update section, three options are available:

Ask before downloading program components - the default option. You will be prompted to confirm or refuse program component updates when they are available.

Always update program components - program component updates will be downloaded and installed automatically. Please remember that a computer restart may be required.

Never update program components - program component updates will not be performed at all. This option is suitable for server installations, since servers can usually be restarted only when they are undergoing maintenance.
