Compiler

Generator uses metaeditor compiler for final build of your EA or script.
You will need to setup both compiler and output path.

Compiler
Look for metaeditor compiler in your MT4 or MT5 terminal installation folder.
Compiler is called "metaeditor.exe" or "metaeditor64.exe".

Typical path looks like this:
C:\Program Files (x86)\xxxxxx\metaeditor.exe
Here xxxxxx is your broker name or terminal installation folder.
Output Path
Look for output path for generated EAs, scripts and indicators.
On Windows 7,8 and 10 it is inside C:\Users\ folder under your username.
Full path is rather long and some directories might be hidden.

Typical path looks like this:
C:\Users\xxxxxx\AppData\Roaming\MetaQuotes\Terminal\#####\MQL4
Here xxxxxx is your user name and ##### is long hexadecimal number.

Typical compiler and output setup example:

mql options

Edit following parts based on your folders:

mql options 2

This should be enough but if you still can not get it to work check items below:
