What Exactly Does This Mean??
 

Sorry for such a newbie question. Just getting into these PC games and I don't understand what this means. Here's an example:

Install the game - Full Installation.
Replace the original ARMA.EXE file with the one from the File Archive.
Play the Game!

What exactly does this mean? Cause when I try and start a game, I click it, and all it says is that the application failed to start cause it couldn't find some .dll file. Thanks to anyone that could help me out with this.

Obviously, you need to read the forum FAQ first on how to use cracks in general as well as on how to report problems with cracks properly...

Well... Some basic copy´n´paste/overwrite windows-file-operations should be handled by the user before getting any deeper into this... Do you even know what an archive is and how to handle it?
