Problem at wareing [PROTOTYPE] for PC

[Ineedlotsofhelp]

Hello! I dont know is it allowed to ask help at wareing problems. But I hope someone offers his hands to help me. This is really bad problem.
My OS is Windows Vista Home Premium

So...
I downloaded Prototype for PC from ThePirateBay. I torrented it with uTorrent and it was succesful. My computers knowing friend helped me at the process.
I used PowerISO to mount it. I did everything like he said. He got the game to work good with XP.
So. Mounting was ready. I went to My Computer and Doubleclicked on L Drive CD/PROTOTYPE/PC or something. My friend told that the Prototype setup opened immediately when he clicked on the same icon! But on me it goes to Prototypes folder and does nothing!

Please help me, this is very bad problem and I want my version to work 
PS: Sorry about my bad English. Im Finnish, so It might be not good.

Hello. Welcome to the site. 

I used to mount some games years ago when I was really into PC gaming. So I know what you mean by mounting a disc on your hard drive as an image. So when you start up the game it looks to the hard drive image of the game thinking it is a CD or DVD.

One of the best methods I know of to doing this is described below in a video tutorial I found on YouTube. It should help you out.
