If you look @ source code:

Code:

if ($argc<3


... then you must understand, that this script is written for php CLI --> php command line interface. So:

1. Install php to windows computer
2. copy sploit file to php folder
2. open command prompt and navigate to php folder
3. run php CLI from command prompt

If you want more detailed tutorial, let me know Smile
