The version string refers to a legacy reverse-engineering utility built by a group known as Purebeam. In the early days of algorithmic trading, MetaTrader 4 compiled its editable source code ( .mq4 files) into executables ( .ex4 files) using a relatively straightforward bytecode structure.
The EX4-to-MQ4 Decompiler (specifically variations around version 4.0.224-432) is a reverse-engineering software application designed to convert compiled MT4 files back into a human-readable format.

: This specific decompiler was developed for MT4 Build 509 or lower . It uses a byte-code scheme that was completely replaced by MetaQuotes in 2014 starting with Build 600.
Starting with Build 600, MetaQuotes overhauled the compiler to generate machine code rather than byte code. This makes files compiled since 2014 virtually impossible to decompile with this tool.
At that time, MetaTrader 4 compiled programs into a lightweight bytecode format that was relatively easy to reconstruct. The version sequence (including 4.0.224.1 , 4.0.392.1 , and 4.0.432 ) belonged to these early reverse-engineering setups. The version string refers to a legacy reverse-engineering
Never run a repacked decompiler on your main trading PC. Use a Windows 7 or Windows 10 virtual machine (VMware/VirtualBox) with no internet access or trading accounts installed.
Most "repacks" or "cracked" versions of these old decompilers are bundled with specialized malware. Once executed, they can scan your system for MetaTrader credentials, passwords, and crypto wallets.
The V4.0.224.1 decompiler repack offers a range of benefits for traders and developers, including: : Sites offering "repacked" or "activated" versions often
The compiler stopped producing the simple bytecode that older decompilers relied on.
