Indicator calls another indicator, folder location issue

ok, I try to write an EA,

expert uses iCustom to get some values from Indicator1, Indicator1 calls Indicator2 for some cals
all objects are in standart MT4 folder bu got error like
Indicator1 : Error! C:\Program Files (x86)\MetaTrader\experts\indicators\Indicator1.ex4 cannot be found.

why it goes to Program Files (x86) and how to change the settings, I have mq4 files

You must copy the file in the right folder. To find the right folder, open your platform, then click File > Open Data Folder > MQL4 ... then in the MQL4 folder you will find the indicators folders. Once your tool is in the right folder, restart the platform.
