How to Fix MT4 Old Version Error?

The MetaTrader trading platform is improving every couple of months. Developers make updates, new corrections, and fix bugs.
What does the “Old version” error message mean on the MT4 or MT5 platform?

MT4 old version error represents an error that shows that the trader has an old version of the MetaTrader platform installed on a PC or phone application. This version is not compatible with MT4 servers anymore. In this case, the trader needs to update the current version of MT4 or MT5 software.

Can you download Metatrader’s old version?

Unfortunately, you can not download old versions from the Metatrader website officially. MetaTrader desktop app is created to update the old version to the new one automatically. Only the latest stable version can be used. Even if you go to the Metatrader website and find MT4 release notes, you can read about them, but you can not download earlier versions.

If you need to investigate something in old MT4 versions, you can unofficially download MT4’s old versions from the forums.
