What is your operating system?
I am using windows 7.
Try this.
1) Put Antietam disk in pc.
2) Click start button on task bar click on computer option
3) Right mouse click on cd or dvd drive where the game is and select option open in new window.
4) Minimise window so you can see your desk top in background.
5) You will see a folder called Campaign Antietam while over the folder hold right mouse click button down and drag folder to your desk top you will be asked do you want a copy there click yes.
Now you have the game on your pc.
You now must update the game with the latest patch from the hps website.
When you have the patch downloaded select browse and find antietam folder on the desktop open folder and click ok. this will load the patch. Try out game if it works you have loaded the patch in the right place if it does not work then you have put it in the wrong place.
Then follow Dukematts instructions.
First…….save the Banshee down load to your desktop.

Second….open the downloaded folder “Antietam Graphics package”

Third……manually drag and drop the oob files from the “Antietam Graphics package”into the main game folder

Fourth……open the “info” folder in the “Antietam Graphics Package”

Drag “ leaders bmp” and “units bmp” (one at a time) from the "info" folder in the "Antietam Graphics Package" into the “info” folder in the game.
