I got a really bad situation when I tried to install or place indicators on the new build 574 or 600 on my broker which provides me MT4 platform. This new build brings a lot of issues for old products and many people are very disappointed and pissed off because of all this. But for those who updated their platform it works fine if the EA is simple and does not use any .dll.
Below are simple steps how to place your Indicators/Experts into new MT4 platform
1. Open your MT4 platform
2. Click File -- Open Data Folder ( Here you will find a folder called MQL4, this is the new "home" for all your .ex4 or .mq4 files you have)
3.1 Place your experts .ex4 or .mq4 files into MQL4/Experts folder or
3.2 Place your indicators .ex4 or .mq4 files into MQL4/Indicators folder or
3.3 Place your scripts .ex4 or .mq4 files into MQL4/Scripts folder or
3.4 Place your templates .tpl files into templates folder (it is located just as you Open your Data Folder)
and so on for other files of yours
4. The Final step is to restart your MT4 platform and You are good to go
