Hi,
You need to open AYClient.bat. Not yt-dlp.exe
yt-dlp.exe is the command line downloader ayc uses.

EDIT:

Your Windows install is missing some dependencies needed for python.

Install Visual C++ 2015 (13MB) from here https://www.microsoft.com/en-us/download/details.aspx?id=48145

thank you. I already have installed Visual C++ 2015 .. and it still doesn't work.
I open yt-dlp.exe because the problem is in it.
I have solved the by installing UpdatePack7R2-20.3.12 for windows 7. and ayc works now
Thank you very very much. for answering me.
and forgive me for my bad English.
