Searching for an is a trip down a dangerous path. The software is a relic of an older version of MetaTrader and is no longer effective against modern protection schemes. More importantly, the "repacks" found online are high-risk targets for malware.
A decompiler attempts to reverse the compilation process, turning the machine-readable .ex4 back into .mq4 . The Version 4.0.224.1 Context
