The problem is that you did not use quotation mark " (U+0022) around -hostkey value, but left/right double quotation marks “” (U+201C and U+201D). WinSCP (and any other command-line tool I know of) does not recognize these.

The same problem ,I also face," Too Many parameters for command 'open' ".Still I can't figure out that.Even While I omit 'Host-key' part,Error skips.But struck further.
Can I create,hostkey or SSH key by Pageant/Puttygen key generator.than use it in Command.Or while connecting with OPEN command,Remote PC will automatically share the SSH key for authentication.

Unless you provide more details (the script itself) I can only point you to:
