Vista - Unable to run application VISTA

Hello,

I am trying to run an application, actually is the instalation set up file. However when I open it, it show the following mess "There was a file access problem. You have to be logged into Windows as a user with Admin rights", even if I run it as a "Run as administrator"" option.
Could you please help??

Thanks in advance

I suspect this program is too old and non-compatible with Vista.What is program and his version?

Thanks Flavius, yes you are right, this is a game Age of Empires.
Actually Readme doc says:

A. Installing Age of Empires III

To install Age of Empires III, you must have administrator rights on your computer and your computer must be running Microsoft Windows® XP.

so I guess is non-compatible w vista?

Any suggestion?>

Thanks for you help!

I understand the game is already installed,you can't only run game..
Find folder where game is installed and change permission:You have to give for USERS group MODIFY right to this folder:
