1. Navigate to the MT4/MT5 Installation Directory

  • Right-click on the MT4/MT5 shortcut on your desktop or in your start menu.
  • Select Open file location.
  • This will take you directly to the root folder/installation folder.

Copy all necessary DLL files such as fix folders, DLL files, launcher.exe, and terminal.exe into the root folder/installation folder of MT4/MT5.

3. Run Launcher.exe

Use launcher.exe instead of terminal.exe. You can create a desktop shortcut to make it easier to access. You will need to use the launcher every time you open the terminal to ensure the DLL files work correctly. If you do not use the launcher, the DLL files will not function properly.

Ensure that everything has been copied correctly to the root folder/installation folder of MT4/MT5.

5. Configure Expert Advisors

For some products or EAs, you may need to add certain URLs. Open launcher.exe, go to Tools > Options, select the Expert Advisors tab, check Allow DLL imports and Allow WebRequest for listed URL, and enter the required URLs in the provided field.

6. Copy the EA File

Copy the EA file by navigating to File > Open Data Folder, then go into the MQL4/MQL5 folder and copy the file to the appropriate folder.

7. Load the EA onto the Chart

Load the EA onto your chart. At this point, the product should be active because the DLL files are working correctly.
