Current desktop support baseline
Since 1 July 2025, Exness lists MT4 Build 1440 and MT5 Build 4755 as minimum supported desktop versions. Open Help → About in MetaTrader to check the build. An older installer or unsupported build should be replaced through an official download route.
Safe installation sequence
- Open the Exness Personal Area or official platform help page.
- Confirm whether the trading account is MT4, MT5 or Exness platform.
- Download the matching installer; reject mirrors and unsolicited “modified” packages.
- Verify the publisher shown by Windows before installation.
- Launch the terminal and check its build number.
- Select the exact trading server and enter the trading-account login—not the Personal Area email.
- Open a demo chart and place, modify and close the smallest suitable practice order.
