youtube-dl not valid windows 7 program

[Maquett]

I am unable to run youtube-dl, system W7 61bits HomePremiumFamilial.
I wish to donwload the video from culturebox (links on the pic joined), i have already succeeded to download via stream capture softwares the 1600+ little files, that I am unable to join and play (f4f Flash media manifest). I hoped youtube dl will do the job, but the program does not work on W7 (used the windows version indeed).
any help please ???

It looks like youtube-dl is not in your PATH. How have you installed it? Downloading the exe and placing it in the current directory (That would be C:\Users\Dominique) or any directory on the PATH should suffice.

Thanks; even in the repertory Windows 7 C:\Utilisateurs\Dominique it does not work , i got in the command window the message (in french) access denied, and the pop up window (in French) youtube-dl.exe is not a valid Win32 application
As you can see, i suceeded yesterday in downloading the 1600+ files (with a plugin for firefox) , but I am unable to join them into an mp4 file.

I am not sure what joining into an mp4 file has to do with youtube-dl, it just downloads. Can you put youtube-dl.exe into a location you have write access to, and then post the output you get when running that?
