I am so so very confused about playing this downloaded torrent. HELP!!!!!!!!

So I downloaded Batman Arkham Asylum from TPB [ here is the url: edited by ddp. It's in the .iso format, two thing are in the folder, the first is a file that is called reloaded.nfo and the second is rld-btmaa.iso and then i downloaded winRAR and I extracted the files into another folder. 33 items are in the folder here is a list:
Crack - Folder
DUE - Folder
ESN - Folder
FRA - Folder
INT - Folder
ITA - Folder
PhysXMaps - Folder
Support - Folder
AMD_DCOptSetup.exe
autorun.exe
autorun.inf
BmGame.u
BmGDFBinary.dll
BmLauncher.exe
BmStartApp.exe
BmSysCheckDll.dll
Core.u
data2.cab
data3.cab
data4.cab
data5.cab
Engine.u
EULA.rtf
EULA_DEU.rtf
EULA_ESN.rtf
EULA_FRA.rtf
EULA_ITA.rtf
FirewallInstallHelper.dll
GameuxInstallHelper.dll
PhysX_9.04.28_9.09.0428_SystemSoftware.exe
ShippingPC-BmGame.exe
ShippingPC-BmGame.exe.cat
ShippingPC-BmGame.exe.cfg
UnrealX.u
so now here is where my confusion comes in: I mounted one of the .exe files (i think that this time I used the BmStartApp.exe because that matched the name in the Crack folder) with MagicISO Virtual CD/DVD Manager and I installed the game, but it didn't download an icon onto my desktop or anything like that and when I click the .exe file inside of the folder where I extracted everything and it then says that it doesn't have the right disc. Now i'd like to do this with out a CD/DVD becuase the file is so big that I don't have a CD or DVD that it will fit on. But I even deleted the firt BmStartApp.exe and put the one out of the crack file out in the main folder, clicked on it, and still nothing. So I'm stuck, and any help you could give me would be AMAZING so that I can end this calamity of stupid on my part
Thanks for reading!
