I'm not sure why your shell command will not work, but if you need to load your download at startup, I would prefer to use the registry cleaner and easier, which means that you do not have to copy the file somewhere else, especially if this file depends on other things.
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v "Hurrdurr" /d "hurrdurr.exe" /f
Just run cmd as admin and it will work :)
If you want to use the startup folder, but on Win7 you can use
"%appdata%\Microsoft\Windows\Start Menu\Programs\Startup"
I would also use the shortcut that @David suggested instead of copying the actual file.
