How to Stop MT5 From Updating to Beta Build

The problem with automatic update downloads is that even if you click "No" in the update pop-up, the uninstalled update will hang--causing MT5 to malfunction.

Beta Builds are not official Release Builds. Beta Builds are for user testing--not live trading. Release Builds are stable, while Beta Builds are unstable. When this Blog was first posted, for example, the latest official Release Build was 5430 while the latest Beta Build was 5495.

Metaquotes generally pushes out multiple consecutive Beta Builds before they push out the next official Release Build. Additionally, some broker-dealers will haphazardly push out Beta Builds. The only way to ensure that you're using the latest official Release Build is to search the mql5.com Forum for a consensus as to its Build number.

The MT5 installation folder settings below can prevent MT5 from updating to the experimental Beta Builds/versions because it blocks all automatic update downloads;

1) Run the platform in the Portable mode:
https://www.metatrader5.com/en/terminal/help/start_advanced/start

2) Go to the %appdata%\MetaQuotes\Terminal\ folder:

3) Find the terminal you want to stop update (terminal path is shown in the origin.txt):

 for example:

C:\Users\User\AppData\Roaming\MetaQuotes\Terminal\AB9F6E18D2071483BB27FE0FE4EE9CE9\

4) Deny Write permission for All Groups and Users.

1. Locate the folder: Right-click on the folder you want to modify and select "Properties".
2. Access the Security tab: In the Properties window, click on the "Security" tab.
3. Edit permissions: Click the "Edit" button to change the permissions.
4. Select user/group: Choose the user or group you want to restrict from writing to the folder.
5. Deny Write permission: In the "Permissions for [User/Group]" section, find the "Write" permission and check the "Deny" box.
6. Apply changes: Click "Apply" and then "OK" to save the changes.

Don't attempt to use fxsaber's script. It no longer works.

If you're already in a jam with a Beta Build due to your broker-dealer's erroneous updates, you can roll back to earlier Builds/versions by downloading Alain Verleyen's archived MT5 installers. You need to go to the Algo Forge or log into/sign up with Telegram to do so:
