The button
Every green Download App control on this preview uses one outbound address and the rel value sponsored nofollow. The visible label is only Download App.
There is no path on this host that ends in an install file. A request for one should 404. The preview server is the same idea: unknown paths return the not-found page.
The button does not change if the open photograph is Games or Casino. One shell, one outbound control.
This note does not describe the page that opens after the click. That page is not this host.
More from the same capture
One label, Download App, everywhere the green control appears. The preview does not offer a second label such as a file name. A second label would imply a file.
The relationship attribute is sponsored nofollow, plus noopener and noreferrer because the link opens a new tab. That is the whole outbound policy on this host.
