default mt4 account always pop up

 
Hi im trying to copy a signal here in mql5. I have 3 different mt4 terminals installed on my computer. I want to copy the signal using IG-LIVE broker but when i hit copy a window pop up with a green button that says "start copying in metatrader". Once i hit that button another option comes that says "https://www.mql5.com wants to open this application." with a button that says open metatrader and here is when my problem comes. When i hit that button always open forex.com mt4 terminal and i dont want to use that one. I want to use oanda or IG.com. It looks like default mt4 terminal for mql5 is forex.com terminal and i dont know how to change that. Any help here....Thanks in advance
 

You can subscribe directly from the Metatrader instance you want to copy.
"I want to copy the signal using IG-LIVE broker" - yes, you open this Metatrader and subscribe directly from it -
