What are you talking about ?
There is no problem to run MT4 on a 64-bits OS.
There will never exist a 64-bits MT4 version, forget it.
I think you guys don't understand the programs compatiblaity issue between 32 bit and 64 bit and I already lost some thousend buckses trying to run the MT4 with no errors but failed. Thats why prgram producers releases different type of platform compitable with the operating system to run whther 32 bit or 64 bit.
How do I run 32-bit software once I have installed 64-bit Windows?
Windows 64-bit provides a 32-bit compatibility mode called WOW64
(Windows 32-bit on Windows 64-bit) that should run most if not all your
not all brokers run MT5 plaatforms
also lots of products I already bought from mql5 runs MT4
