Struggling so hard to export mesh to Blender

I’ve seen all the YouTube videos and threads on here about it but it’s still not working. Whenever I go into S4S and try to export something it says “unable to locate your blender installation, would you like to download it now?” And I have it downloaded and it’s on my desktop and doesn’t show up anywhere in my files except in the downloads tab. I saw someone say something about putting it in applications but I don’t know where that is on my computer, I have windows. In the setting it says blender path is “C:\ProgramFiles\Blender Foundation\Blender\blender.exe”
when I downloaded it I just had it download on my desktop which I don’t think is the issue Bc this is my second time trying after uninstalling and trying again when I was having the issue earlier…Any help us greatly appreciated I’ve been trying to figure this out since 9 and it’s 12:40 now so I’m loosing it
