Downgrade Metatrader 5 issues

 

I want to downgrade my metatrader 5 terminal because i have an expert advisor that only works on earlier build. The thing is when i replace the terminal64.exe and try to start it nothing happens. It works fine on my laptop and the terminal starts as i should but on my station and my vps its not working.I even tried to remove the mt5 completely and also removed the appdata folder but it still not helps.

Fix it; it is broken.
