Need Help PLEASE!!!

[morningstar6969]

I am trying to add a no cd crack and cant get access, Ill explain everything and hopefully someone can help me, Im very noob at this so explain how as detailed as possibe, thanks. I am running Vista and trying to add the crack for Midieval 2. I have the crack that came with it and another I downloaded. The one that came with it is already opened but when I try to replace the .exe file it says a shortcut can not be placed here. So I either need to know how to get around that or, the one I downloaded is a .rar file. When I try to open it directly int the game file it ask if I want to replace the original and I select yes, I get the error can not create midieval 2 exe. access is denied. Can someone PLEASE explain to me how to get around this? Thank you
