update script fails

[5shekel]

encountered this on windows 7 64bit.
ehwn i start the update machcnism for the .exe version
the update script will try to pause for 5 seconds using
ping 127.0.0.1 -n 5 -w 1000 1>NUL
but this will stop and not continue after batch file initiation.
i am left with this files.

youtube-dl.exe
youtube-dl.exe.new
youtube-dl-updater.bat

what i usually do is manually edit the batch to remove the pin command and run it again.
