  Two things---one, a Lua string delimeted by the single or double quote use
the '\' as an escape character, so what Windows is seeing is not the string
you are giving it; you'll need to double up on the '\' character.

  Two:  Since the filenames in the string contain no spaces, the double
quotes around them are not necessary and can be removed.  So the following
examples should all work (each example on one line, in case it wraps):

os.execute('"C:\\Program Files\\WinSCP\\WinSCP.exe" /console /script="C:/puttyfac/ExtraPuTTY/Bin/winscp/winscpftp.txt" /log="C:/puttyfac/ExtraPuTTY/Bin/winscp/winscplog.log"')

os.execute("\"C:\\Program Files\\WinSCP\\WinSCP.exe\" /console /script=C:/puttyfac/ExtraPuTTY/Bin/winscp/winscpftp.txt /log=C:/puttyfac/ExtraPuTTY/Bin/winscp/winscplog.log")

os.execute('"C:\\Program Files\\WinSCP\\WinSCP.exe" /console /script=C:/puttyfac/ExtraPuTTY/Bin/winscp/winscpftp.txt /log=C:/puttyfac/ExtraPuTTY/Bin/winscp/winscplog.log')

os.execute [[ "C:\Program Files\WinSCP\WinSCP.exe" /console /script="C:/puttyfac/ExtraPuTTY/Bin/winscp/winscpftp.txt" /log="C:/puttyfac/ExtraPuTTY/Bin/winscp/winscplog.log" ]]

os.execute [[ "C:\Program Files\WinSCP\WinSCP.exe" /console /script=C:/puttyfac/ExtraPuTTY/Bin/winscp/winscpftp.txt /log=C:/puttyfac/ExtraPuTTY/Bin/winscp/winscplog.log ]]
