Downloading from mql5-site & getting mql4-buy error

Hello Folks.

Do you know what's going on on mql5, if one wants to download (in this case a free) tool, the "Real and Tester Trading"
"https://www.mql5.com/en/market/product/28421?source=External#"
and the site will not give you the download, but the browser asks for external application "mql4buy)?

I have portable MT4 installation, and would (probably) need to make manual installation anyways. What external tool is mql5-site trying to get? I don't get it.

I guess the above tll could be a good too for manual backtesting, any alternatives?

Thank you. This is good advice in general. I however don't see how this will help me getting the mentioned file/EA downloaded from mql5 site, or am I missing something?

What happens when you go the normal way?
