Make sure that the software is "vista ready". If it is not then you will have problems installing the game. Vista is not very backward compatible when it come to software, especially games. Try going to the vista support site, often time you can find fixes for these kinds of problems. Good luck.
may be the game inside cd is corrupt or your system's specification is different than that of game's system's requirements.
but there is no fault in your computer
its just fantastic and outstanding
rather i could have been affected by trojans
May be Medal of honor afraid with your PC Specifications..
