Stupid question, can I download JUST the setup.exe?

basically im downloading RDR2 and the setup got automatically deleted for some reason, which never happens. I want to run the setup tonight so its read by tommorow but if I have to download the whole thing again itll take ages. I still have it on Qbittorent since I was seeding, so can if I download the torrent again, can I just get it to download the setup?
