Insufficient logging

[mohmad-null]

Downloaded 1.7.1 from Github for Windows 7 - it's a single .exe

When I downloading something, for a fraction of a second at the bottom of the screen it says "Downloading CLI" or something to that effect.
But really it doesn't download anything (I guess my firewall, but that's a me problem). So I end up with a youtube-dl.exe file that has 0 bytes. I can fix this myself.
The bug is that none of this downloading or failing to download is in the log file at all. It should be. Similar to the other bug I reported, you should always log errors!
