MT4 Build 1478: “Has newer unsupported version” error with EX4

 

Hello, I have a problem loading an Expert Advisor in MetaTrader 4.

My terminal version is:
MetaTrader 4 Build 1478
Date: 22 August 2026

The EA is named GOLD_MT4.ex4 .

When I try to load it, MT4 gives these messages:

GOLD_MT4: has newer unsupported version, please update your client terminal

cannot load ...\MQL4\Experts\GOLD_MT4.ex4

The important point is that the same EA file is reportedly working correctly for other users.

My MT4 terminal is already Build 1478, so I would like to understand why this EX4 is considered a newer unsupported version on my terminal.

The file size is 159,542 bytes.

SHA-256:
9184E24BCD46720DB4C5E976BFCFCE0E86AC0FFEA9AB2563513F1DEA08A2135A

Can anyone explain what could cause this and whether there is a compatibility difference between MT4 terminals?

The last stable build is 1470. You are running a beta. Your supplier compiled with a even newer beta.

Ask your supplier to compile with the stable version for release.
