Can't download indicators

 

When I identify an indicator to download, I click on Download then a box appears asking if I have MT4 installed so I click on "Yes, I have MT4" but it does not accept that. If I click on "No, I don't" it goes off and starts downloading MT5 which I don't want at this stage. I'm running MT4 on a Mac. Screen shot is attached. Any ideas?

Many thanks for any illuminations!

 

You can download it directy from Metatrader:
just fill Community tab in Metatrader with your forum login and forum password, go to search on the toip right corner of Metatrader, write the name of indicator -
and download it.
