Live Update

A system of automatic updates is built into the terminal. It allows to get informed about and install new versions of the program promptly. This system is always enabled, it is impossible to disable it.

Updating Procedure

The terminal checks for new versions of the program when it connects to the server. If a new version of any of the terminal components has been discovered, it will be automatically downloaded in the background mode. At that, the following entry will be displayed in the terminal journal:

10:13:37.730 LiveUpdate: new version 4.00 build 563 is available

On default, the updates are downloaded to the following folder (depending on the operating system used):

Microsoft Windows XP:

  • C:\Documents and Settings\username\Application Data\MetaQuotes\WebInstall

Microsoft Windows Vista and higher:

  • C:\Users\username\AppData\Roaming\MetaQuotes\WebInstall

Here "C" is the letter of a logical disk, where the operating system is installed, "username" is the account in the operating system, under which the terminal has been installed. Downloaded updates are available for all terminals, the updates are not re-downloaded for other instances of terminals.

After all the updates have been downloaded, the below entry will appear in the terminal journal:

10:14:17.180 LiveUpdate: finished

To apply the updates, the terminal should be restarted.
