ProtectionID v4 question.

[WhatWhat]

I dont know if I am doing it right but I dont think so because it doesnt detect any protection for max payne 2. This is how I do it,

I open the program (obviously) and I press scan
Then I scan all the exe files available

Yet doing this says that no protection was found. Am I doing it wrong or is it true that max payne 2 does not have any protection??
