Testing a demo EA : automatic opening of default MT4. How to change it?

 

Hi

 

when i click on "Free Demo" to test an EA, i have a window that pops up and shows

"Yes i have Metatrader"  or "No i have not "Metatrader"

 

then if i click yes, it opens the default MT4 because i checked the wrong box and it automatically opens default MT4, but i wanna change that :

how can i have the previous window where it lets me whoose which MT4 to use?

 

thanks a lot!
