guys,please help me

I ve just downloaded medal of honor pacific assault from u-torrent.It showed me 2 files an mdf and an mds which i easily opened using isobuster.it extracted many files including one called setup.i opened the file and pressed the installation icon.i choose language and the it says’the install shield wizard will install MOHPA on your computer.Click next to continue'.I press next and it shows me 2 sines.the first one says’windows are anable to find medal of honor passific assault code.exe’The second one says’the registration number was not correct.instalation cannot continue'.And then it closes automaticly.Now the strange is that it hasnt even asked me for registration number.But if i go to another file called’support’i can find an icon called Medal of honor passific assaulttm code(cd key).if i open this one it asks me for the seriale number(i know the seriale number).I put it i press next but nothing happens.I just closes.I am desperate.Please tell me what to do in order to install this **** game.

You could try and buy it legitimately.
sorry but no talk of illegal downloads, serials, cracks ect and seeing as that is the only thing thats gonna help you, I will have to lock this topic.
