To install Client Terminal, it is necessary to download its distributive and launch it. Then it will be necessary to choose a directory for installing the program there and follow the Installation Wizard tips. After the terminal has been installed it will run automatically.
Terminal can also be installed over an installed version of it. At that, all terminal settings remain as they were in the preceding version. Exceptions can be: DEFAULT profile and template, as well as standard MQL4 programs included in the delivery set. This is why it is not recommended to change standard templates or profiles, but to create MQL4 progams named uniquely.
If there is a need to work with several accounts simultaneously, the corresponding amount of terminals must be installed in different directories. At that, each terminal has its individual settings, except for registration details and interface language, that are stored in the Registry.
