Installing FarCry 2

I downloaded a torrent from one location, and installed the game, after I installed, I checked through the download folder for a shortcut that starts the game. I did not find that, I did though click on something called FarCry2.exe.
That brought up a box that told me it had to be activated. I clicked next on that and it brought me to a place where I could enter a SERIAL(Im guessing this means a CDKEY) in a box. Now I downloaded a crack made by Razor 1911. I then opened that in WinRAR and clicked on it. It brought up a box that said “this application has failed to start because Dunia.dll was not found, reinstalling the application may fix this problem”.
I do not believe that there is any reason to reinstall, just some glich or w/e. I am kind of lost here as I can not find how I am supposed to get past this SERIAL request. Help would be much appreciated as it is my first time doing this and I am pretty lost.

You can’t just click and run it from Winrar. You have to extract it and copy it over the original Farcry2.exe in the Far Cry 2\bin folder
