Running two separate instances of Joy2Key

[Kilgore.dfa]

I'm not sure if that's the right place but simply i want o open 2 separate Joy2Key instances with a batch file. So far that opens only 1 instance.

start "joytokey" "C:\JoyToKey\jtk374en\JoyToKey.exe"
start "joytokey2" "C:\JoyToKey\jtk374en2\JoyToKey.exe"

I need to modify it so it can open 2 at the same time.
